I've been looking around the forums to try and see if anyone is doing similar, but doesn't appear so.  My plan (not the best I know so please give minimal critcism  :-[ ) is to run my tank for a week with no fish and then get a few as its for the kids birthdays so can't really make them wait the 1-2 months for a full cycle.

I've been chatting with @Littlefish who has kindly agreed to donate some mature media when the time is right and I'm just setting up my plan of attack to start this weekend. I also have a bottle of "Fluval cycle biological enhancer" to put in over the 1st few days (I know these products don't get the best wrap but thought as I have it, it can't do any harm)

Current plan:

Saturday - Wash Substrate, tank decorations etc and setup tank with filter, heater, substrate, decorations, water (with tap safe) and let it run for 24 hours to get water to temp and make sure everything is running as expected.
I'll take  water readings for everything immediately and then after 24 hours and then on a regular frequency as the cycle progresses.

Sunday/Monday - Visit LFS and pick some Elodea plants to help with the cycle and maybe some surface plants - duck weed seems to be recommended although there does appear to be some bad reports too, any advice?  Whilst I'm there, going to have a look at the local stock and based on my community fish selections see whats available and compatible.

At this point I know I need to get some ammonia in the tank so advice on the best course of action here would be appreciated.  I can't get seeded media ( thanks again @Littlefish) until Tuesday due to logistics of not being around to receive and install until then, so at this point I'm a little stuck as to the best way to move forward, do I need to get some ammonia to add during the initial week that I'll have no fish?  or could I just drop in some fish food and let it rot and produce ammonia that way (not too sure how long it takes to rot?)

Tuesday - Friday - Mature media arrives and installed, then looking for advice really on the best course of action from here. Assuming more ammonia at some point + more readings.

2nd Saturday - up to 90% water change and get 3 or 4 of the hardy fish from my Community Selection and then introduce the fish gradually to the tank, allowing time for water temperature to equalise and introduce a bit of tank water to the bag over several minutes to give them time to acclimatise.

2nd Saturday onwards - regular measurements and water changes as required to keep the levels down.

Please feel free to tear my plan apart, that's my reason for putting it up here in the 1st place TBH.  The only part that can't change is adding the fish on the 2nd Saturday, earlier is fine, but can't be any later.  ( I know, hit me with the beating stick  :vcross: for being cruel to fish, but I'll be on the ball with water monitoring and as soon as levels rise I'll be doing immediate water changes to help them along the way.  :fishy1: )

Thanks again for all the advice so far.

What filter are you getting for the tank? Just asking to work out what type and volume of filter media it will take.
I understand the issue with birthdays, and it would be so wonderful for you to be able to introduce fish at that time.

In order to minimise any potential damage to the fish, the more mature media we can get into the filter, the better. I have a lot of mature media available, from several internal and external filters.

@Sue if I can get enough mature media to Bazza to fill around 50% of the filter, would it be possible to add some ammonia to boost bacteria numbers Tuesday to Friday, water change Saturday morning, add birthday fish later in the day.

As a slight aside, I thought I'd post this as it made me chuckle...

It's the first time I've noticed someone advertising this stuff as "suitable for fishless aquarium cycling"

Just a couple of comments:

Adding ammonia will keep the mature media fed till the fish arrive, but you must remove every trace before putting the fish in.
Our town has a small family run DIY shop which sells Kleen Off ammonia. But read the label as there are several products in the Kleen Off range and I once heard of someone trying to cycle with oven cleaner  :o

Throw the Fluval product away and get Tetra Safe Start.
When these cycling products were first invented they based the formulation on what worked in sewage treatment where both ammonia and nitrite are quite high. Although they managed to use a species of ammonia eating bacteria that work in fish tanks, they chose a nitrite eater which didn't because those bacteria need high levels of nitrite to survive and there are only low levels in a fish tank - once cycled the level is so low our test kits can't measure it.
Then a chap working for a company called Marineland did some research and discovered which bacteria the nitrite eaters in fish tanks actually are. Marineland and the chap who made the discovery patented or copyrighted (whichever is the correct term) the use of these bacteria. The chap left Marineland and set up his own company and because he was named on the patent/copyright he could make a product with the correct nitrite eaters. This is Dr Tim's One & Only which is hard to get in the UK. Marineland was taken over by Tetra, and they rebranded the Marineland product as Safe Start, which still uses the correct nitrite eaters.
Tetra Safe Start is sold widely in the UK - just make sure the bottle is still in date.



I would set up the tank and let it run to check all the equipment works, get the plants, then add the mature media when it arrives.

Since you really do want to do a fish-in cycle, get the barbs first.




Duck weed is not sold at fish shops, it is an unwanted weed for most people. But if you can cope with having a 'weed' it will do a good job of taking up ammonia. You may find some shops that have it in their tanks; if you find some, ask for it. The reason it is a weed is because it grows very fast and takes over. But this is what you need during a fish-in cycle. Once you have all your fish you can net it out and throw it away, it will have done its job. if you can't find it in a shop, there are people on Ebay selling it.
Alternatively, buy another floating plant. I used to have Salvinia which I bought on Ebay but it all died off a few years ago during a very hot spell when condensation from the lid dripped on it and rotted the leaves. This applies to all floating plants with furry leaves such as Amazon frogbit and water lettuce. Duckweed does not have furry leaves, and neither does water sprite if you can find that. Water sprite can also be grown rooted in the substrate. And elodea can be left floating as well as being planted.

Long term, the fish you are thinking about do not like bright light as they come from rivers with overhanging trees. They will appreciate whichever floating plant you get.

I've just gone back to the other thread to check tank size. As soon as we know what filter is being used I think I may be able to provide all the mature media. If so, then at least it will give the fish the equivalent to a newly cycled tank. That should be a bit safer for them.

Ah, you've reminded me - I stumbled across it for the first time the other day while looking for something else at this website https://www.realaquatics.co.uk/ which I don't actually recall seeing before.

I just had a look and unless I missed it they only have the marine version of One & Only. But they do sell that company's ammonium chloride for cycling. That's a form of ammonia.

Hi, Filter specs are here: http://ciano.pt/en/produto/emotions-pro-80/

There are also some details next to the photos attached to this post.  There is 1 long full height square sponge and then 4 compartments for other elements I'm not too sure what they're for, but I did notice 4 packets of something before I left for holiday.  Can check more when I get back on Saturday.

Efficient and functional biological filtration
The aquarium is equipped with a CFBIO150 Ciano® biological filtration system, with more filtration power due to its horizontal filtration (filter masses). The filter is equipped with a high performance motor 260 l / h, an efficient 150W heater and the consumables (2 Water Clear “M”, 2 Bio-Bact “M” and 1 FOAM “L”), for a chemical filtration, biological and mechanical. Optionally, you can attach a fully immersible digital thermometer with integrated sensor.

Equipment Included
1 Biological filter CFBIO150 Ciano®;

1 LED lighting system CLE80 Ciano® (24W – 38VDC);

1 Converter LED(27 - 40VDC);

1 Water Pump 260 l/h;

1 Heater 150W;

2 Doses WATER CLEAR “M” Ciano®;

2 Doses BIO-BACT “M” Ciano®;

1 FOAM “L” 30PPI Ciano®;

fcmf's link is to the correct Dr Tim's One & Only. My excuse for not seeing it is that I have rotten cold and having to stop reading to sneeze etc.  ::)

Yes, the product in fcmf's link is Dr Tims, and Tetra Safe Start is available at Pets@Home https://www.petsathome.com/shop/en/pets/tetra-safestart-50ml as well as smaller shops, Amazon & Ebay.

Dr Tim's ammonium chloride https://www.realaquatics.co.uk/drtim-s-ammonium-chloride-solution-for-fishless-cycling-60ml.html They also have an Ebay shop.

But also look on Ebay & Amazon for ammonia and look for the KleenOff Multi Purpose Household Ammonia. A lot of other brands contain detergent and are no use.

Thanks for the links to the tank & filter information.
I can send mature sponge media big enough for that filter.
Looking at information on replacement parts, it says to replace the foam every 90 days - DO NOT DO THIS, as you will be throwing out the bacteria and essentially starting your tanks cycle from scratch. Foam/sponge just needs to be gently rinsed in used tank water during routine maintenance.

Fab! Really appreciated!
And yep, read all the forum posts on washing filter in tank water and refitting.
One question, do I replace the main long sponge with your media or 1 to 4 of the smaller ones? Do I need to use the 1 to 4 smaller ones at all?

Replace the long sponge with the sponge that I send. You may need to trim to size, as my sponges are more square, but I'll check the measurements of the sponge for your filter and make sure you get enough.
Looking at the information available for your filter, the 4 white things are 2 x water clear cartridges, and 2 x Bio-bact cartridges.
I don't know anything about this filter, so I'm only going on what it says on their site.
The water clear cartridges are described as chemical filtration, to keep the water clear, reduce algae, etc. According to another site it is activated carbon, and has to be removed when using medication.
The Bio-bact is described as biological filtration, and says it is "an excellent habitat for nitrifying bacteria". Again, it says to remove these cartridges if using medication.

If a filter comes with activated carbon it is common to remove it, and fill the space with more sponge, then just keep the carbon for removing any left over medication after a water change when a medication regime has been completed.
If any of the others have any experience with these filters or cartridges please let us know if they are surplus to requirements, or if we could go with more sponge. thanks.  :)

Sue you are a genius with these thivs but just wondering about your choice of the barbs for the first fish... I have never kept barbs but I know harlequins are incredibly hardy having been through a fish in cycle with me before I knew any of this stuff.  What do you think?

I have never had actual harlequins, just Espe's rasboras, but I have had cherry barbs. 3 of the rasboras died within a few weeks, but the barbs proved very hardy until the whitespot outbreak. I don't know if it was the whitespot, the raised temp for weeks, or the attempts find a medication that was effective on this strain of whitespot, but they all died, having been very healthy fish up to that point.
Of course harlequins might be hardier than Espeis rasboras.

If you have had harlies and found them to be hardy, then either those or cherry barbs for the first fish. But whichever are chosen, the rest of the shoal should be added before starting a second speciees.

Started my initial fishless cycle Saturday, added ammonia yesterday up to 3ppm, got some cloudy water today which I suppose is to be expected, @Littlefish (thanks again) has kindly posted some mature media which should arrive tomorrow and I'll get that straight in.  I have a query about whether to replace the current sponge I have or to add the mature media into a 2nd compartment which is available with my system as shown:



Would it matter if I had 2 sponges in the filter i.e. would it cause issues with circulation or cause the pump to work harder than normal?  Or would it just be easier to do a straight swap?

The thinking around having 2 is that I could always replace 1 after a healthy lifetime (assuming years) and leave 1 in, and then alternate if that makes sense? How does everyone else do it?

Can you tell us exactly what the various media are please? I can recognise the sponge, but what are the white blocks on the left of the sponge, and in the box at the bottom of the compartment on the extreme left?

Usually it is better to leave out any carbon and replace that with sponge. Or replace the existing sponge with Littlefish's sponge. It is considered better to have mature media early in the direction of water flow if at all possible; that way any bacteria/biofilm that becomes loose gets washed into other media and helps start it to grow there.

Hi Sue, the white blocks are according to the manual 2 Doses of Water Clear "M" and 2 Doses of BIO-BACT "M", I've not added them in yet as I'd seen advise elsewhere to leave them out, so effectively the 4 white block section is empty at the moment, the bottom left is the pump and the tube on the right is the heater.

Littlefish's media can go in the space where the white blocks are supposed to go; or cut up both her sponge and your sponge and put bits of both in each section. You would need to cut them lengthways because there should be no gaps in the direction of water flow - side to side - or the water will go through the gaps rather than through the sponges.

The mature media I have sent is as follows:-
2 x complete inner sponges from Superfish Aquaflow 200 filters, with the carbon replaced with ceramic media, and some extra squares of sponge. The Superfish sponges are approximately 6cm x 6cm, with a length of around 9cm. When I got them I removed the carbon and replaced it with the ceramic media. Both of these together came to less than 24cm (length required to replace existing sponge), so I've also included several squares of sponge to make up the total length, to make sure there were no gaps in the sponge chamber.
I would suggest using at least one of these inner sponges in its entirety, perhaps cut your sponge to a length of 15cm (ish, check what you need before cutting, and cut a bit bigger so you have to squeeze the sponge in to avoid gaps) to fill the rest of that space. I'd suggest that you use the second mature sponge in its entirety to replace the carbon cubes, and pieces of the other sponge to plug any gaps between the other cubes.
There is a lot of mature media that should reach you today, and if you can get it all into your filter then there is a very strong possibility that your filter could be able to process 3ppm ammonia within 24 hours, with a bit of luck.  :)

I've noticed that your second filter chamber is narrower than the first, so you wouldn't be able to use an entire mature sponge to replace the carbon cubes as the sponge would be too big. If you cut the sponge length-ways it would probably fit. You would lose the ceramic media, but that wouldn't be the end of the world.
The two complete inners are "more mature", and have come from more heavily stocked tanks than the off-cuts of sponge, so use as much of the two oblong sponges as possible, even if you have to cut one up.  :)

Yeah, I'll take my sponge and hack it to make it fit and then put your media in where it came from so it hits the water 1st and hopefully passes some of the good bacteria through onto my original sponge.

New media has arrived and been installed (thanks again @Littlefish - packaging was fantastic!!) I managed to install about half of my original sponge in the separate compartment too so hopefully not too much disruption.

One things I've noticed on the glass (this was before the new media was installed) was a small something, looks like a snail to me, but wanted some advice, it may have arrived on the plants I put in over the weekend.

Anyone got any idea what it is, and is it safe to leave in?

It's a snail  :)

I can't tell from the photo but the two most common 'pest' snails are tiny ramshorns and physids - the latter are referred to as pond, bladder, tadpole and pest snails. Google should find some images for you to compare. And yes, it did arrive with your plants, either as a snail or an egg.

They are not bad. I know a lot of people will do everything they can to eradicate every last snail but they are actually an important part of a tank's ecosystem. They are only a problem when they take over, and the main reason they take over is because they have a lot of food - uneaten fish food. As long as you don't over feed the fish, once you have some, their numbers should be kept low. They will eat algae and dying plants so even if they don't get even a tiny spec of fish food they will still find enough to eat.
Fish do not need as much food as you'd think. Mammals use a lot of what they eat just maintaining body temperature. Fish don't do this, their body temp is regulated by water temp so their need for food, weight for weight, is less than mammals. As a very rough guide, a fish's stomach is the same size as its eye. Feed the fish as much food as is equivalent to one eye per fish  :)



I have tiny ramshorns and physids that came free with plants, and I have bought malaysian trumpet snails and nerite snails for my tanks.

I've also taken reading over the past few days (pre-mature media installation) to see how things where getting on with a few strange results.

It's a snail  :)

I can't tell from the photo but the two most common 'pest' snails are tiny ramshorns and physids - the latter are referred to as pond, bladder, tadpole and pest snails. Google should find some images for you to compare. And yes, it did arrive with your plants, either as a snail or an egg.

They are not bad. I know a lot of people will do everything they can to eradicate every last snail but they are actually an important part of a tank's ecosystem. They are only a problem when they take over, and the main reason they take over is because they have a lot of food - uneaten fish food. As long as you don't over feed the fish, once you have some, their numbers should be kept low. They will eat algae and dying plants so even if they don't get even a tiny spec of fish food they will still find enough to eat.
Fish do not need as much food as you'd think. Mammals use a lot of what they eat just maintaining body temperature. Fish don't do this, their body temp is regulated by water temp so their need for food, weight for weight, is less than mammals. As a very rough guide, a fish's stomach is the same size as its eye. Feed the fish as much food as is equivalent to one eye per fish  :)



I have tiny ramshorns and physids that came free with plants, and I have bought malaysian trumpet snails and nerite snails for my tanks.

Thanks Sue, I'll leave the little blighter for now, he is tiny though, I thought it was spec of dust!

Your graph is interesting. It would appear that the Safe Start has had an effect, albeit a small one so far. The ammonia reading fell slightly and nitrite appeared shortly after adding the Safe Start.

Don't take too much notice of nitrate. It is very difficult to measure accurately at home. My younger, son who used to work as an analyst for a water testing company, is highly amused by our nitrate testers. Part of the problem is that one of the reagents is not soluble, so we have to shake and shale that bottle to distribute the powder throughout the liquid.


The next few, post Littlefish's media will be most interesting  :)

Have you added any ammonia since Littlefish's mature media went in the tank?

In that case we can't know just how many bacteria the new media has added to your tank. Add 3 ppm ammonia as soon as you can, and measure everything 24 hours later.
If ammonia is still 3 ppm (which I doubt), don't get fish just yet.
If ammonia and nitrite are zero, when you go for fish you can get almost all your planned list. But if neons are still on the list, wait a few months before getting them as they do better in a mature tank - one that has grown a whole host of other micro-organisms.
If there is some ammonia and /or nitrite when you test after 24 hours, do a water change to remove them before you go fish shopping - ideally the evening before so the water temp has time to settle. Then get one shoal of fish and proceed as for a fish-in cycle. This means test for ammonia and nitrite every day and do a water change if you see either above zero. Once you've had zeros for 7 days, get the next batch, test every day for ammonia & nitrite etc. Even if the mature media hadn't added enough bacteria to remove 3 ppm ammonia, and the nitrite made from it, it should have added enough to cope with a lower bioload, which means that even if you can't get all your fish you will be fine getting some.

Ok, we are now at 2ppm, the API kit only measure 2 or 4ppm so thought best to keep it lower that 4 so looks good on 2ppm, will monitor over the next 24 hours.

Near at the end of my 1st week fishless/fish-in cycle and it appears our attempts at fast tracking my cycle have failed.  Whilst there were promising signs middle of the week once I'd added the mature media (thanks again @Littlefish ) and tetra safe start, it appears I now have no bacteria and I'm effectively 1 week into a fish-in cycle.  I've put the most recent Ammonia drop down to the plants helping out.
 My fish-in cycle will start on Sunday (4 x Cherry Barbs) after I do a major water change tomorrow to get the ammonia down to safe levels.  Just wanted to thank everyone for the fantastic advice and help along the way up to now.  I'm kinda looking forward to the challenge of keeping the fish as safe as I can during the fish-in cycle.  I'll keep you updated with my progress.

Not too sure if this is the right thread, but I've noticed my plants don't seem as healthy as they used to be, some algae by the looks of it on some and the Elodia has strands hanging from some of the leaves.  Anyone seen this before?

The second plant is dying because it is not an aquatic plant!! It cannot survive in aquatic conditions. Sorry but you have been miss sold this. Get rid of it before it rots and destroys your water quality!

I don't think elodia grows roots, but is that what they look like?

I've seen a lot of places selling plants that are not truly aquatic in their bunched plants tank.
If it's any consolation @Bazza2000 I have previously bought exactly the same plant that you have, and ended up throwing it away. I'd suggest spending a little bit more money and purchasing the potted aquatic plants, which also come with labels containing planting information which you can double check online.
As for the elodea, that can also be used as a floating plant, and grows roots at fairly random places along the length. Good to see yours are rooting.  :)
