Honestly I have been thoroughly confused about pumps and ratings lately. The pump I am using on the old scc65 is an aquabee 2000l, which is supposed to put out approx 450lph of air, I had to dial down my air intake to halfway open and dial down the water output as low as it would go to get the bubbles to rise up in the neck. Which means it barely runs a skimmer body rated for 65 gallons... The deltec that this pump came off of was rated at 125 gallons. Now the sc 150 rated at 150 gallons has a very close in capacity pump in the atman 2000. The part that is confusing me is if you look at the bm-nac7 it is using an atman 2500 and is rated at 185 gallons. But if you look at the bm 180-cs it is using an aquabee 2000l and rated at 240 gallons...
