Hey there, I am about to upgrade from 2 heavily planted medium (20L & 29g) sized tanks to a large (75g) tank. I am planning on utilizing everything from the smaller 2, to set up the larger 1. This way I get to keep as much good bacteria as possible, plus it's more cost effective.
Will have 4 smaller sponges and a hang on back filter, would these be enough for filtration/oxygenation, or should I get a couple larger filters to carry the size of the tank? Would I need to look into power heads, or bubble walls?
I don't want to lose the bacteria from the smaller filters, 1 because they've been going for a good 2 years now, and 2 it would mean I wouldn't have to wait for the tank to cycle fish less.
All advice is appreciated.
