Quick verdict
The go-to filtration upgrade for a frame pool that won't stay clear on its stock cartridge pump.
Ideal for
- Above-ground frame pools
- Hot climates
- Owners upgrading a weak cartridge pump
Not ideal for
- In-ground pools (undersized)
- Very small pools (stock pump is fine)
The full picture
Frame pools ship with undersized cartridge pumps that struggle in heat; swapping to an Intex Krystal Clear sand filter pump is the most common above-ground upgrade. Sand media filters longer between maintenance and handles bigger pools, and it's sized to match Intex/Bestway frame pools out of the box.
