I am looking to do something a little different in my pool. I am needing about 225gpm and I don't have a whole lot of space. I am using 3 Clean and Clear 200 sq. ft. cartridge filters. My question is, do I need 3 different pumps or can I run them all inline with one big pump. My first instinct is that I need one pump per filter rated at 75gpm but I wanted to make sure. It just doesn't seem that if I had one pump rated at 225 gpm, that it would work very well with 3 filters inline rated at only 75 gpm. Or is it possible to use one pump and have it pump to all 3 at the same time (in parallel) instead of having them all in series.
