We are new pool owners of an old pool (bought an old house with an old pool). We opened the pool about 3 weeks ago. Had a local shop open and turn all on. Theool stayed green and cloudy and very slowly began to clear but after 3 weeks still could not see much past shallow end. Chlorine and pH seem to be correct. The pool has a DE filter and I added some DE on Friday and the familyrorted it looked better o. Saturday and could see bottom of deep end (12 ft) on Sunday. They swam a bit and when I got there it was cloudy again. A few questions:
1. I got the K2006 test kit to measure CYA and it appears to be 0. I ran the test and the black dot didn't come close to disappearing. Would a 0 reading be correct possibly? And if so, I need to add stabilizer, correct? Is there a non-pool store alternative?
2. When I've added DE I mixed about 16oz in a bucket of water and sucked it into system with vacuum hose. Our pool has no skimmer so I added at the pipe the vacuum attaches to (not sure of name). After adding I can see some DE blowing into pool. Would some of this be normal or should there be none coming back in?)
3. This pool is 50k gallons according to previous owner. 48' x 18' and 12 feet deep. How long should I expect ittotake to clear?
