Well, one thing is for sure - I now know more than I thought I wanted to about pool filter systems. I can't find much (in some cases - any) flow/head info on AGP pool pumps. I emailed Hayward and asked for that information specifically about the 1 hp 2 speed PowerFlo Matrix. We'll see where that leads.

At this point, I'm planning on the S210T Pro Series filter and the SP15922S PowerFlo Matrix pump. If I was sure I could still vacuum effectively (with a manual vacum), I'd strongly consider the SP1750 1/2 hp pump. We are leaving for a few days of vacation this month and I'm going to wait till we get back to order.

I think the system above will clean my pool in about half the time it takes my current system. If I throttle the pump so there's no sand washed out on high, then only use high for backwash and vacuum, this system ought to be a good one. My 14" filter has about 1.06 sq.ft of filter area, the S201T has more than double that. I think I'll be running about the same GPM - if you believe Intex propaganda. I know the Intex system I have blows stuff through the sand.

Am I kidding my self?
