A month ago I set up a new 20 gallon tank for my betta. I used the filter cartridge from his 5 gallon to help cycle the 20 gallon. Water has been testing great (0-0-5). I still have the old filter cartridge hanging in the new tank. Think it's safe to take it out now? I want to start my 5 gallon back up again with another betta and wanted to put the cartridge back in there to assist with that cycle.
Fish in the 20 gallon are:
(1) Betta
(1) Nerite Snail
(2) Amano Shrimp
(5) Panda Cories
Is a month enough time to get the 20 gallon set up with its own good bacteria?
