I was considering running an eheim pump on my remora pro skimmer. currently I have a mag 3 and but I wanted to upgrade the pump and I have heard that mag 5 and 7 can be loud. eheim has a 600 GPH pump and a 300 GPH pump, has anyone tried them on the remora pro. I currently have a eheim 1260 for my return and feel it would be too much for the skimmer but the next size down is around 300 GPH and I don't know that it would be an upgrade from what I already have.
