Hi,
I'm new here. I've kept fish before, but have never had much luck for very long. Never understood about new tank syndrome before.
Anyway, I've always used a UGF. But I don't want to go there this time.
Basically I bought a 29 gallon starter kit. It came with a Top Fin 30 HOB filter. The filter came with one new cartridge. There's a lot of empty space in there even with the cartridge inserted. The instructions say that the bacteria grow on the "filter frame", but what does this mean? Can I just take the cartridge out and replace it every month without destroying the bacteria colony?
My next question is, can I put an extra sponge in the filter box to give the nice bacteria a place to grow. I don't want to end up changing the filter cartridge and completely destroying the bacteria colony.
Thanks for the help,
Don T.
