My 55 g has one baby goldfish the ammo is 0/.25 u know how it looks and the nitrites are zero and nitrates are five. I have two babies goldies that have been in qt over two weeks it's been cycling the whole time. Should I just move them to the 55 or would that throw it behind?? I could steal a filter from my established 55 tank but I don't want any problems with it. I have a aqueon quiteflow and 2 whisper 30 but one is just a couple days old
