Hey bassguy, what kind of filter setup are you using on the 90-gallon-tank? Maybe I need to clean my canisters more often?, I really hate taking them apart. I feed 1-large feeding a day in the morning, then do a 90% water change to vac any un-eaten food from the bare bottom.
During the change my tank really is stinky, I mean when you walk into the bedroom during the change you can smell it.
I know 6 bass in a 90G is a lot, but there still only around the 5-6 inch range, with 2 large Eheim 2078's I would think the BARE tank would be less stinky. I feel I HAVE to do the 90% change daily otherwise the water quality would go down the tubes.
Maybe bass are just more stinky? I'm still running my temps around 87-88.
