Prizm is not a good skimmer. Pretty much a waste of money.
if u gonna get a prizm just spend that money on a remora a better rated skimmer....unless u have a sump, then u have a better range of skimmers for ur needs.
I was looking at the Prizm earlier. Why do you think it's not good? What about the Skilter Filters? (I'm going to use it for a 75G FOWLR).
I had a prizm and a seaclone they don't pull 1/8th of the skimmate my remora does. If you want info on skimmers and such click on the search on the toolbar and put the names of both skimmers you posted and listen to others who speak from experience. They stink.
Skilter is an antique technology has come so far since that was invented but if you want to waste your money, go ahead.
