Pool filter sizing

My current sand filter has cracked and I am looking to retrofit with cartridge filter. I have a small pool 10x20x4 6000gal. Current pump is 1hp. What size filter would be right for me?

Hello Matthew - You could probably get by with a Hayward C250. That is a 25 square foot cartridge filter. However, I would recommend going a little larger. Something like the Hayward C500 would be more ideal. You wouldn’t have to clean the 500 as often and the cartridges would last longer.

Thanks that what I was thinking. Would the C751 be too big? I can get a good deal on one. Cheaper than the 500

The C751 wouldn’t be too big.
