Thanks Mike! I will not mod the feeder pump! As for using a T off of my return, I am only running a mag 7 and it matches my overflow prefectly! I have ball valves on both my return and overflow and the ball valves are both wide open! I dont have much of an income, cause I am only an E3 in the army! The rio is an extra pump I had laying around! I have been running a coralife SS65 with a rio 1100 for over a year with no problems! I know they arent the best, but you use what you got when your trying to feed the family and your reefing hobby! LOL! Thanks so much for your help!
