Bad filter?

Recently moved into a house and inherited a neglected above ground pool. Previous owner had new liner and filter replaced in 2018 and did absolutely zero with it from there. As in left it run for two years straight rain and shine. I have gotten the water from a deep army green to a milky aqua/light green (that’s another thread topic in itself) but was wondering if I need to replace the filter? Or maybe sand in filter? Or would I be good to get some filter cleaner? Any and all advice appreciated.

Welcome to TFP.

Sounds like your sand filter needs a deep cleaning.
