I originially had a magnum 350 on mine and I hated it...I took it back to petco and got the cascade 1000 yesterday (Have a 90 gallon tank)...so far I really like the cascade it is super quite and it comes with a spray bar that evens out the output flow...the bad thing is it only does like 265
gph's and my magnum did like 350
gph's.....but I am well willing to give up the power as it seems it is a better canister and easier to work with.....what about everyone else?
They are both rated up to 100 gallon tanks
