I will be ordering (by the end of the month) and installing a 30ft AG Pool. I was wanting to put an extra return (180 degrees apart) on the pool, to help water flow around the large circumference and help with potential algae problems around the ladder areas. I have read TFP Pump Basics and Hydraulics 101. Finally to my three questions: First, is the 1 hp pump big enough or would a 1.5 HP be needed? Second question, would the slow speed setting on the two speed pump filter as good on the Pentair SD-80 Sand Dollar Filter with ClearPro Technology with near DE filtering qualities? Second question asked another way, Do people with DE Filters have any filtering problems with a Hayward Power-Flo Matrix 2 speed pump when set on the low speed? Do you think a 2 inch suction line and a 1.5 return line would work well in this system?
The below pump,filter and system setup is what I came up with.
Hayward Power-Flo Matrix 1 hp 2 speed Link
Pentair SD-80 Sand Dollar Filter with ClearPro Technology Link
Hasa Commercial 8 gallon Liquidator Link
Other useful info about my possible system.
I plan on puting gravel in bottom of filter and using regular pool sand with a small measured amount of DE media on top.
The pump system will stay next to the pool.
I plan on hard plumbing it in with quick disconnects and 2 inch suction line and 1.5 return lines.
My automatic suction pool cleaner will be a Hayward AguaBug
I will use the Hasa Commercial 8 gallon Liquidator for my bleach dispersal unit.
All help and comments will be appreciated as I am going to start ordering by the end of the month.
Thanks in advance for the great info from the TFP Community.
