I'm having some issues with not being able to totally clear my pool water. I accidentally let the water get green during a cold snap about 2 weeks ago and since then I can't get it to sparkle.
Here are my test results as of just a few min ago
CYA 30 (it was 35 the other day but we got some heavy rain)
We run a swg for 2-3 hrs each day. And I have a sand filter that runs for about 8-10 hours per day. 24ft rounds pool.
Let me know what I should do first! Thanks so much.
