So, I've managed to get all my chemicals into pretty good shape, yet yesterday the pool started to cloud up. Today, I can't even see the drain in the eight-foot deep end. There is no green. As first look, the pool looks great. But with a visibility of about 7-8 feet, it's pretty disappointing as I've really been focused on getting it great. Here are my numbers from this morning:
I intend to bring up the CH to near 400 tomorrow and my CYA dropped more than I expected. I stopped replacing water the other day, yet the CYA dropped from about 90 to 65 after I stopped. I cleaned the filter really well today. The elements are nice and white again. I've reduced the SWG's output 5% in my continuing effort to find its stable setting.
After I had done the shocking and brushing last weekend, the water was crystal clear for several days. The cloudiness appeared yesterday. The FC hasn't dropped below 5 since I installed the SWG last weekend.
What's going on?
