Ok well after talking to Al a couple time this weekend and last week. Sounds like we are both getting ready to dive into upgrading our ballast systems. I am going with 3 1" intakes, 3 Tsunami 1200's, all 1" hose lines and 1" vented loops. I am leaving the drain alone for now, well I mean the pumps. I am on the fence with the "Y" and one way check valves for the drain side. Hopefully I will purchase everything Monay and go to work. I was really going to go with the signle intake and 3 tsunami 800's but if I upgrade to the 2300lb gravity 3 system I would like to have the faster fill time of the 1200's.
