I have a pup tank that is 220 liters. On this tank i run a Fluval 404 canister, has bin working great. But today i decided to put in a Eheim 2252 (1200l\h). I could clearly see that the rays reacted on it as the flowrate i added was a turnover by 6. Is this too much on a pup tank? what do you guys out there run?
