why to move 1200gph? Assumption of a newbie i guess. Figured the more water turned over in an hour the better. Plus I was going to use it to creat flow eliminating the need for power heads. I have since purchased the maxi 1200 with timer combo. Think I should drop down to a mag 5? that would give me the 4 times an hour turnover.
