I currently have a Top Fin 30 that came with my 29 gallon. It is working fine, but I am finding that I need more room to customize my media. My KH is low, so I have a bag of crushed coral; I have a polishing pad; and I have an extra bag of bio tubes stuffed in there in case I need cycled media for another tank. I recently had to remove the activated carbon from my filter pad because it was falling apart. So I want to have room to add activated carbon separately. Also, I want to add some nitrate reducers. I know I cannot stuff anything else into this HOB. I am about to buy a canister for my 55 gallon, and I do not think I can justify buying 2 canisters to my husband. My question is: will the aquaclear 50 be sufficient to fit all this stuff inside?
