Canister Filters for a Serious Newbie
First I've learned so much from this forum and I want to thank you all.
I've a 45 gallon tank with high lighting and automated pressurized CO2 system. The plants are doing great and all is pretty much great. Even my algae problems are pretty much gone. Yeah!
I am thinking of switching to a canister filter (Rena Filstar XP2) instead of the bio wheel I have. I have 5 angelfish and one pelco in there I'd like the improved filtration.
So--here's what I don't get about the canister filters..do I need a air stone...or is there enough oxygen already with the canister areation/biofiltration?
