What size sand filter would I need?

[Big Mike]

I need to replace my 1984 Hayward sand filter, and I'm trying to decide which filter would work best with my set up. I have 1.2 hp pump circulating a 22,000 gallon inground pool. Thanks in advance for some advice.

I'm going to guess that a 200lb filter would be just right.

Why can't you fix your old filter? It's just a tank with laterals and a multivalve on top.
