Last year my water turned green, and I came here for help. You expertly guided me to clear water using the SLAM process.
Well- I'm back.
Our water has been cloudy, but not green. It gets a little more clear, and then a little more cloudy.
We are in Ohio, and have had tons of rain this year. Tons
Our moderate temperatures have kept out pool temp between 79-81 for the past 3 weeks.
This week, I decided to take our chlorine level from 4 to 8-10 to kill any algae that may be present and get our water back to clear. Due to the fact that the water was not green, I hoped this would work.
I started dumping lots of liquid chlorine in the pool. I've taken the level as high as 11, and never let it get under 5. I've used at least 25 gallons of chlorine this week doing this (the pool is 42,000 gallons). Now I'm wondering if I still need to slam.
At 8AM, the chlorine was 10. At 7 PM, it was 6.5.
My CC has remained at .5 for most of this week.
Do I need to SLAM, or can I get by without closing the pool?
Notice the barely visible white drain cover in the bottom of this blue plaster pool.
