I am upgrading my 15'x48" Intex pool pump system from the junk 1000 gph to a sand filter system. I can get the 2100 gph or the 2650 gph for only a $10 difference in price but the issue is that either filter system is big for my pool. BUT, next year I plan on upgrading to the 24'x52" Intex pool, which will need the larger pump system.
I plan on plumbing it for dual intake, one from a thru wall skimmer and the other with suction down near the bottom of the pool. I will use ball valves in the system to limit/restrict the flow so I can make either pump system work. My question is, because of my planned upgrade, which of the pumps will be best for the larger pool? Is the 2650 gph even too much for the bigger pool or would I be better to just have the larger capacity, period?
