Hello,
It's been a few years since I've needed to come back here for help, but Im not sure what I am currently dealing with. Up to this point this year my pool has been clear. Last Saturday (June 24th) I noticed a bit of cloudiness. That afternoon I brought my chlorine level up to around 16 (CYA is 30). By the evening, the cloudiness was gone and back to clear. Here is where something must have went wrong. The next morning we left for vacation. Knowing I would have no one to watch the pool, I turned off the filter figuring I would deal with any algae bloom when I got back. We returned yesterday (July 1st) and I was surprised to see that my pool was still crystal clear. I turned on the filter. I figured my chlorine was probably low, if not gone (should have tested), so I added two gallons of 12.5% liquid chlorine to my pool (27,000 gallons) to get up near "shock level". 30 minutes later, I notice my pool is now clear and green. Tested Chlorine at 16. My initial thought was algae. But the water is clear, and it is not consuming chlorine quickly. Then I thought maybe just dirty water from the filter and lines, but I haven't noticed any visual change since. I know I messed up by keeping my equipment off with water that had high chlorine levels (didn't think of it, until it was too late), so I'm thinking that maybe it caused some damage somewhere resulting in this green water. I've had metal issues before, but when I had chlorine levels high, they would stain my liner and steps. I currently have no staining and chlorine is near 15, so I'm not sure if it's metals. For now, I plan on waiting until chlorine levels are normal and then test PH & ALK (should have done first) Anybody have any ideas as to what the green water is from? Thanks for any help!
