I currently have a heavily stocked 55 gallon tank with two HOB petco power filter 65. I would like to add a canister filter to my setup. I have been going crazy reading up on all the different canister filters ie: Eheim, Rena, Fluval & Magnum; However it seems that every filter has its negative reviews. I am looking for one reasonably priced, very quite with a high flow rate and multiple stages of filtration. I would love some feedback or suggestion which I can use in order to make a good decision.
