I think I know the answer to this question, but wanted confirmation from some with more expertise than I. We are upgrading to a 75 gallon tank from a 20. We have been working on cycling it for almost a month and last Sunday we saw our first traces of Nitrates. Testing yesterday indicated between 5-10 ppm of nitrates. Our ammonia and nitrites have been 0 all along (I seeded with the filter cartridge from the 20 gallon tank). We have been doing a fish-in cycle - with about 15 danios, so I have been testing daily for ammonia and never saw anything detectable.
So now that I have the nitrates I am figuring I am about ready to start adding the fist from the 20 gallon into the new tank to join their friends. The new tank has 3 danios, 4 tiger barbs, 2 mollies, 3 speckled cory cats, 1 albino cory cat, and a Pleco.
So how should I move the fish? Should I move one species at a time and wait 3-4 days for the bb to catch up in the 75 gallon? Or will it be safe to move them all at once now that I have bb in my filters?
If it makes any difference I have 2 Aqueon 55/75 filters, each with some extra Polyfiber pad in the back of the filter (I have a total of 2 cartridges that came with the filter, and the other 2 slots are filled with the same polyfiber padding).
Thoughts? Thanks in advance.
