Advice wanted on setting up a fresh tank

Hi,
Been a while since I was in here ...
Looking for advice on best way to set up my daughter's new tank.
She had an aqua one 28l and after some issues with the light we have replaced it with this one

 https://www.ebay.co.uk/itm/Small-Nano-Aquarium-Fish-Tank-Coldwater-Tropical-LED-Lighting-7-14-29-Litres/401209909447?ssPageName=STRK%3AMEBIDX%3AIT&var=670791096535&_trksid=p2057872.m2749.l2649

 Since her last fish died a few weeks ago we kept the tank running and didn't over clean it or the filter. Is there likely to be any functional bacteria left? I was wondering if we would be able to run the old filter in the new tank or add the filter media to the new filter, however, it has a filter system I am unfamiliar with an in hood filter system. 

Also wondering if bioballs work ....

Just looking for best way to speed up cycling.
Last time I partly fishless cycled but only really got anywhere when changed to fish in cycling.

All advice welcome. Ps I'm an established fish keeper, just not done a new set up in years.

Hi there   :wave:

If it has only been a few week then there is a possibility that the bacteria in the old filter are only dormant, and not dead, so using the media from the filter to seed the new filter will speed up the process.

Then follow the sticky describing fishless cycling https://forums.thinkfish.co.uk/fishtank-filtration-and-cycling/fishless-cycling-how-to-do-it/ to make sure that you have enough bacteria prior to adding fish.

Hope it all goes well and that you keep us updated on progress.  :)

There may well be quite a lot of bacteria alive in the old filter, though they are probably dormant by now. How long it takes them to 'wake up' depends on how long they've been dormant.

There is nothing to say you have to use the filter in the hood of the new tank; if you could manage to fit the old filter in there, use just that instead. But if it worn't go in (eg nowhere for cable to come out) move as much media as possible into the new filter, cutting up sponge to make it fit. You would just need to make sure that there are no gaps round the edges of any sponge or the water would go round it rather than through it.




As a matter of idle curiosity, what were the issues with the light on the old tank? I have an Aqua One AquaSpace (described as 32 litres but actually holds 26) and that came with a clip on LED. I unplugged it a year or two ago and the transformer-plug came apart in my hands. I replaced it with Hiddom light!

It was a fluorescent light in a sealed plastic case but it appeared that water was getting on the inside. In the summer my husband replaced the light and thankfully was in the room at the time as the light almost immediately started flashing. My husband turned it off but said that the whole fitting was very hot indeed. We carefully tried another light in case it was a faulty bulb but had the same result. As the tank is bright pink and is not generally looking so great and the hood is discoloured on the inside likely due to an overheating light we decided a new tank was the safer option as it is in my 14 year olds bedroom.

Thanks. Will definitely transfer the media over. It cannot harm and may well help.
Also considering cultivating it in my large tank for a while first. If I was to do that how long would be optimal?

Going back to the in hood filter system ... Been reading about how replacement of the media can prevent nasty stuff leaking down the back of the tank .... What are people's recommendations or am I better asking this in the equipment section?

Am considering careful fish in cycling this time ... The fishless only got us so far last time. Preferring to grow bacteria on media and then slowly add fish. I do have all the relevant test kits!  :)

I think with those trickle filters in the hood, if the media gets blocked water flows over the top of it and can run anywhere. Keeping the media clean would stop this happening; they only say to replace it to make money.
But there is another potential problem with trickle filters which mainly affects tanks in areas which are prone to power cuts. If the power goes off, the media could dry out and the bacteria would die.

If this was my tank and I could find any way to use the old filter, I would do that. The usual problem is feeding the filter cable out from under the edge of the hood.

It strikes me that if you used something like a ceramic media instead of sponge then this issue would not present itself... I have seen one of these filters used before, it was filled with plants doing natural filtration as part of a dissertation.  Quite impressive!
