this thing is making me mad, i bought it off of a friend in my reef club and he had the mag 3 hooked up to it and a mag 7 in the sump for his nintey gallon, well when i bought it off of him i coulnt get my overflow and sump to match (i had to restrict the pump with a ball valve so much it made the pump noisey) so i put the 3 from the PS and the 7 on the skimmer, the problem is when i had the 3 on the skimmer it sucked alot of water into it, and now all i have is a 7 for it, i have read about many people using 7s on their remoras and getting good skim but i dont see how, i have the collection cup all the way up and i still get way to much water in it....so what do i do..like i said even with the mag3 it was a little much do i need a mag2 or something or am i doing something wrong
