Day 31 And My Tank Has Finished Cycle

With a fishless cycle, if you used ammonia dosage to give 5ppm you should be able to get 75% of your proposed stocking straight away. So you get het a shoal of both tetras and more fish. The only problem you might have is finding a shop that will sell you that many at once. Even if you say it was fishless cycled they may still object. One chain shop in particular (not the one you mentiobned in another thread  ) has a policy of asking how big your tank is and refusing to sell more than x fish at once regardless of tank size.

I say 75% to give your tank chance to mature, that is grow all the other micro-organisms needed to complete the eco-system. And any fish you want that tend to be a bit delicate are better left till the tank has been running 6 months.


If you used less ammonia than 5ppm, then scale that % down accordingly.

This is a 180 litre tank isn't it?

Both of those would be fine. With 4ppm in a 180l tank, you could get both.



Of course, whatever you decide to do, keep an eye on both ammonia and nitrite daily for several days to be absolutely sure. It is good practice to do this every time you get more fish even when the tank has been running for years.

Hi,
I have just done a 50% water change (10.4am) Now I will check my water in about 35/40mina.

I want to go and get fish between 4.30pm and 6pm. Do I top up my ammonia or not??

Thanks Sue!!!
