Sorry I didn't see this sooner => NEVER increase pump size, without increasing the filter size.

Virtually ALL above ground pools have oversized pumps and undersized filters. Matched sets, like Intex sells MAY be actually matched, but I don't have data proving that.

Oversized pumps:
  • push dirt THROUGH sand filters
  • DAMAGE membranes and grids on DE filters
  • COLLAPSE filter pleats on cartridge filters.

What most pools need is a bigger FILTER, not a bigger PUMP!
