Sediment filter for small pool
I have a small childs pool (2.5m diamater & 60cm deep). I live in the Middle East and we receive a lot of dust in the air so the filter that came with the pool is inadequate. I have a separate pump I can hook up to the pool to provide water pressure, but now I need to filter the water.
Could you suggest an appropriate sediment filter and cartridge. I was thinking of the Pentek 10' Big Blue housing (Item 150239), but have no idea what cartridge to use. I don't want to remove the chlorine, just the dust.
Also how long does a $3 crtridge last compared to a $16 cartridge?
