What size sand filter?


Bronze Supporter
I just pulled the trigger on a 1 hp single speed pool pump, because NO WAY can I ever afford a VS pump for my little 14' pool. I have a 12" sand filter on the current 0.5 hp pump, but I know I'll need a bigger one for the bigger pump, won't I? What size sand filter should I get? Is there a range of sizes that would be suitable for a 1 hp pump?

Got the 1 hp for $139, which is a deal any way you look at it. Gonna wait til next year to get the filter, hoping the ridiculous prices will go down...
