I only have experience with the seaclone 150 and a remora and I have to say the seaclone is quieter, removes more skimmate, and, as others say, can be a PITA to keep adjusted and maintained. Clean the foam filter once a week, keep an eye on the air bleed, and mine produces a lot of nice gunky foam, a very dark and concentrated skimmate, and no bubbles. A real bargain compared to the Remora IMO.
