HI! here! So lets get the flaming over with, Any ways, been doin the fish hobby for a while now. But I just purchased a 125 gallon Tank, I want to go canister filter, and was wanting to know everyones opinions on this, pros? cons?. I have always used Marineland Emperor 400's up to this point. Should Just get 2 of those instead of the canister? I was looking at the Magnum 350 pro set up, bUt I would still need to add a back of tank filter to comp. for the lack of flow. I have 3 very large Pacu's (salad plate size) and a large Pink and brown spotted catfish that will be going in there, and a handfull of community fish for color. Any help would be appreciated.
