I have a 125 gallon that started with 3 ac110s..now i have 3 canister filters and no HOBS. I have the spray bar for 2 of the canister filters at the water line to move the water a bit but it doesnt have the water movement I had with the 3 110s...maybe its just me but my fish dont seem as active now?? am I worrying too much or should I get a couple powerheads or bring back one or 2 hobs? any thoughts?
