Thanks Janet! I talked with a lady at a pool store and she seems to think that my model of pump is ok for my filter. She has the same set up as I do. The 1.5HP is not fully rated and is not like a commercial grade 1.5HP. She had the same problem with sand getting in her pool and said it was her spider gasket / multi valve gasket that needed to be replaced. So she talked me out of buying a new filter since I replaced the guts last year. So I'm going to go try that route and see what happens, but I would still like to know what size filter to get. Or what HP of a pump I need.
Your welcome for the support! I'm new this season actually. And where is everyone? Usually I get a reply a little quicker. Ya'll helped me tremendously with my algae problem and saved me tons of money. The people that work at Walmart give me looks when I walk out with 10 - 182 oz of bleach though. LOL
