Hey Guys,

I am looking at an air pump for my new system there are around 700 gallons of water in this guy. I was thinking about the Danner AP-40, it says the 40 has 2700 cubic inches/ which is 10 gallons / min of flow rate versus the AP-20 which is 1700 cubic inches/min or 7./3 gallons per min.

They also make a 60 (5500 in3/min) and a 100 (9150 in3/min)

What I am hearing from Oliver is that I may need 3500 gallons per hour of flow rate for 700 gallons of water. Not to mention my new system is a Chop II monstrosity. Basement System Design

Thanks
