I have a 18x34 doughboy AG vinyl liner with a deep middle. About 16,000 gallons.
I started the season and got the CL to stay and added the CYA by the pantyhose method and everything was perfect. Test results were great and I added a gallon of bleach every night. I went out of town last weekend and we had a ton of rain and I came back to a green pool. No CL and high pH. So I vacummed to waste like crazy and scrubbed the walls. Cleaned the filters and then kept the CL up to 15 for 3days. The water looks pretty clear now but it's a bit cloudy and I can't get the CL to hold over night. I added 4 gallons last night and 1 this AM and now I just tested at 7PM and here's what I got.
FC - 0 ppm
TC - 0 ppm
CC - 0 ppm
PH - 8.0
Alk - 150
CYA - 0
Can someone help me get this stablized step by step?
I am ready to through bleach in for the night and I want to make sure thats the right thing to do. The dirt devil d1000 is at work vacumming right now so do I need to backwash and then add CL? If it holds then can I add some more CYA tommorow AM? I'm worried about the pH and the Alk going higher.
HELP I'm confused.
