I bought a Remora from the manufacturer about a week ago and it is already doing a nice job of cleaning the "gunk" out of the water. Hangs on the back and is very quite.KsFireman said:I did have a Prizm myself, but I could never get anything other than tea colored water in the collection cup. After 4 months with the Prizm I went out and purchased a Coralife Super Skimmer and I could not be happier. In just one day the Super Skimmer had a dark, thick, coffee colored junk in the collection cup and did more than my Prizm did in 4 months. Don't get me wrong, the Prizm is a DECENT low budget skimmer, but for about $130 at your LFS or around $85 on line you can get the coralife super skimmer which can be used as a hang on the back or an in the sump skimmer and do much better than the Prizm.
Just my two cents worth,
