I went by my lfs for a chat yesterday. I told them I'd be in the market for a 90 gallon tank soon, and possibly a 55 or 60 gallon tank. Once I get these 2 and add them to my 2, 29 gallons and my 10 gallon tank I hope my MTS will go into remission. Anyway, the 110 has the same footprint as the 90 so I decided that would probably be better. The lfs guy told me to go with a wet/dry filtration system and that he would come to my house and set it up. I've read and have been told that these are the most effective and low maintenance filtration systems to get. Their 110 gallon set up comes with 2 Aquaclear 110s (500 gph apiece), which is 400 gph more than the 600 gph wet/dry I'm looking at. I may put the 2 110s on the 60 and go with a wet/dry on the 110. Many have stated they like canister filters and I've been looking at those too. My lfs carries mostly Renas. I could trade the 2 AC 110s for a Rena canister if someone tells me that a canister filter that does 350 gph is better than 2 HOBs that do 1000 gph combined.
