Greetings,

New problem, I’ve never had before. After 10 days of adding bleach (174 oz, 6%) everyday and one box of Borax everyday the pool is still green.
- In ground concrete pool, 24,000 gallons
- Mesh covered during winter, didn’t open pool last season
- Sand filter
- FC 0/0
- PH 6.8
- ALK 80
- TH 200
- CYA 0

No visable signs of algae

PH and FC go up to normal levels but don’t last 24 hours, won’t stabilize. I bought some CYA at Wal-Mart but don’t understand how to add. I’ve had the pool for many years but never had pH or CYA problems before. Thanks
