the link is to the maker of my skimmer and I am thinking of placing a order with them either this month or next month. I use the MRC-2 beckett skimmer ran with a gen-x PCX 55 high pressure pump. It is easy to adjust the amount of skimmate. dial's in pretty easy. over all I am impressed with its performance. just a side note It has been running for about a month so lets see how well it breaks in, but for now I simply love it. my tank is a 180 I just set up.
