I really need help. Thought I had the problem beat but instead I'm beating my head on a rock.
Pool has been green off and on for weeks now. Started I believe when I entered pool. With tan oil on. Lesson learned.
2nd year with pool.
Water gets clear as I add bleach and settlement falls to bottom and I vacuum. Then it all starts again. After vacuuming,water gets cloudy. I dont believe my water has been completely clear with sparkle all summer. I had gotten to much cya in pool so I raised chlorine to compensate based on pool school calculator.
I finally decided to add another pump. Put an Intex 1900 gph pump in and just ran hoses over side. I have been running this pump about 26 hrs now along with skimmer pump and I don't think I see see much change. I checked filter on new pump and can hardly tell it has been used. I expected to see some discoloration but all I see is a few bugs. Water is flowing great and surface water is moving.
I know I havent been able to stay at shock levels but have kept chlorine at correct levels. Most likely that is the problem. We have had tons of rain so I spend alot of time draining water off.
My cya was originally at 70 but I ran out of test supply 2 days ago. Making a wild guess and know I shouldnt but think cya may be close to 50 now with all the water drain I've done. Will order more test supplies.
Current tests are as follows:
Cya 50 ?
Test done with no sun on pool
Test this morning were the same but Fc was 27. Had added bleach last night. App 8 hrs between tests.
I will continue with chlorine as best I can without accurate cya but other than doing that, I'm at a loss as to what to do.
