Since I started using TFP, I have stopped going to local pool store. I bought the recomended TF 100 test kit. My water is sooo Cloudy, I get this fine brown dust-like matter on the bottom (only) of my pool. I have vacuumed to waste several times and it is still there but getting less everytime. I can see the bottom of my pool..BUT my problem is when I (& Kids) get into the pool and go under the water with goggles on, the water is very cloudy. I can not see the whole way across the pool, only about half way across. My "clean" reading on sand filter is 10 psi and it is only at 12 now, so I haven't backwashed in about 2 weeks. I have tried the clarifier the pool store recommended, but nothing has cleared the cloudiness. I have had my pool at shock level for over 24 hrs now and see no improvement. My filter has been running just about 24 hours a day since the end of May (Memorial Weekend). Here are my readings, any HELP would be greatly appreciated. I have been using only liquid bleach to chlorinate and shock.
FC 18.5 (that was bfore I added more to bring up to 19.8 shock level again)
PH 7.8 (Just think it's reading high since chlorine is so high)
