hey guys, i currently have a 75 gallon tank set up, if u check my page, i some lovely babies that are getting big. I bought some bio balls cause in about a month or so, i will be up grading my tank to a 200g tank. i tried to fit the bio balls where my filters are, but no luck, they wont fit. (two 70 g Fluval filters) If i just throw the bio balls in the tank, and have them sit there for about a month or so, will beneficial bacteria grow on them?? and if not, any one have any ideas on how i can get benificial bacteria from my tank and transfer it to the new tank i will be getting?? i don't want to transfer the gravel.
