RedSea Prizm HOB needlewheel skimmer, if you aren't good at making fine adjustments or you are impatient, then this is not for you. You need constant water level for this (and most others) skimmer to function productively.
I used it for about six months on my 100 gal, removed about 16 oz. of thick coffee consistency skimmate every two days, not bad when compared to much more expensive units. Can be submersed in sump as well as used as a HOB.
