New to forum, black algea problem.

Honestly, I think I want to upgrade my filter. It is time for new cartridges and the pool store wants $200+ for a set. Now is the time, I can get a hayward pro grid for a couple extra bucks. Mine is a clean and clear plus 40. I hate it. No back flush. When removing phosphates I have to disassemble and clean sometimes daily. I think I will replace with a 60.

Not finding that model; here's the Pentair brochure: http://www.pentairpool.com/pdfs/cleanclearplusDS.pdf

There is a CCP420 and there are some Clean and Clear filters (no "Plus"), but the lowest they go is a CC50.

The Hayward Pro Grid is a DE filter. Have you ever used a DE filter? They are not very forgiving, and can be rather messy to service.
