Current filter is a Hayward DE60nn, and is shot I am taking it. Pool store want $800 to basically replace all the guts (60 sq. ft DE grids, DE Manifold, and some other minor charges like gasket and sealer.
So I always wished I had cartridge filter instead (smaller mostly).
So with a 30K gallon IG plaster with a 2 HP northstar pump, what size cartridge filter would I require to replace my DE filter?
