I have always run rather small tanks - 20 gallons or smaller - however for my birthday I received a 60 gallon monster (at least it will be in comparison to my much smaller tanks). I have intentions to use SeaChem's Fluorite for substrate and heavily plant the tank, as well as use driftwood. I want to add Gourami's and eventually Discus as well as some other smaller fluffy fish. Yesterday I ordered an Eheim Wet/Dry Canister Filter (2229) it says it is for use up to 159G (this will be my first canister). My question is, with the tank being heavily planted and Discus being so sensitive preferring pristine water will this canister be enough or should I add a second form of filtration? If I need a second form are there any suggestions? Thank you in advance for any input!
