i have a pump that has a 296 gph, then 2 (60) gph. It that too much water current? plus a hang on filter. It's a 40 gallon tank.
The 296 pump came with this thing that adds air into the water. Should I just take that off or should I leave the air going into the water?
5-10x total system turnover per hour is good, so yeah, you should be ok with what you have. You might want to consider using a skimmer and a wet-dry filter.
