I just installed a Pentair Clean and Clear 420 filter and it does not seem to be filtering, the water remains cloudy. I opened up the filter and made sure everything was sitting properly. I must admit that the pool is very cloudy since I wasn't able to clean it while I was installing all new pool equipment. So I had a lot of algae and dirt which I took care of by shocking the pool and using Algaeside. So now I have a bunch of dead algae that does not get trapped by the new filter.
A PB told me that I can add some DE to the filter to help it, does this sound correct, if so how much.
I bought this filter because I did not want to deal with DE, my old filter was a DE filter.
