Help with Blue Cloud that is my pool!

[S-T-THREE]

I am using cal-hypo for chlorination, but I am not sure what fill water means. If it means municipal water I use to fill the pool, I have neve tested it. Regardless, I have not added water for some time due to heavy rains last week that nearly overfilled the pool. I guess I could test those levels and see if it's attributing to it?

No more cal-hypo in your pool. I think you should probably do a partial drain and refill to lower that calcium hardness reading. Don't totally drain the pool, though. Maybe about half.
