I have a 3.3G KK from Petco, running with the Azoo Mignon 60 Generation 2 filter. The cycle is set up, I'm using the API test kit. Well I'm thinking about getting a 5G or 10G tank, I'll use the same filter, so will the BB just carry over into the new tank? Will the new water kill the BB?
Also, sorry for my multiple threads D: I just want to make sure I can keep my Betta safely and happily!
