I just picked up a reef octopus dnw 150 recirculating skimmer. Just curiuos to what feed pump I should use. Its going on my 120 that has about a 30g sump. According to the website it says to use something 1 1/2X the tank volume that makes it about a 225gph pump. Will a maxijet 900 work? What is evrybody else running. I know I could use a mag 2 but there is a huge cost difference.
