I currently have a Mag 9.5 in my Pro clear 125 wet/ dry (that I'm using as a sump). I don't like it for many reasons. First, I believe it heats up my tank. Second, I think that it is too powerful as my return for my 72 bow front. Third, it takes up lots of space in my sump. It is also noisy. I went out and bought an Eheim 1260. I want to set it up so the pump sits on the outside of my sump. Any advice?:iamwithst
