This is my 2 yrs with this inground pool. First year was terrible Bank on property and did not cover the pool. I had to replace the pool system. So everything is new. My problem this year is my pool is cloudy. I have been working on it for 7 days now. Pump running non stop and shocked three times in a week. Still no free chlorine reading. Today i was trying vacuum the cloudy pool but my pump was having trouble priming. After that I backwashed and put DE powder in and it blow direct out of the other side. I think DE is getting in my pool.
