I started a SLAM hoping to clear up the pool before closing. There were frogs living in it. It was a deep murky green. My CYA is at 90. (yes i know it’s high) I tested with the 2006c kit. I’m keeping fc at ~36 as recommended. cc is at a steady .5 every time I test. It’s been pretty expensive and a week into this and $200 worth of chlorine later the pool is still incredibly cloudy. I figured it would have cleared up by now even with the high cya.
I’ve deep cleaned my sand filter. I vacuum blindly but it doesn’t seem to help much. I also brush the walls and floor every day.
I’ve seen some strange behavior from my filter. Pressure has not been rising. It’s at a steady 10 psi.
Adding DE does raise it so it must work right? But then if i turn it off and turn it back on pressure goes back to 10. What could be happening?
Already did a deep clean. I even purchased a sand filter cleaner and let it sit. Backwashed it. Then I opened it up and deep cleaned with a hose for half an hour. Added sand up to the line (was about half an inch low). Anyway still same thing. I take photos of the steps and I haven’t seen any progress as far as how deep I can see. Visibility is like half a foot.
The pool seems to use up about 6-7 fc per day. I’m adding ~3-4 gallons a day. One or two in the morning and one or two at night.
I’m about to give up and just close the pool and deal with it next year. Hopefully cya will be lower at that point after the partial drain and refill. Is it too early to throw in the towel?

You definitely still have a large algae issue. Following the
