I bought a home with pool. Pool is about 12000 gal + attached SPA
Water seemed clear and there was a maintenance person. I decided to do it myself.
There were more twists than in anticipated. The filter cracked, the pool vacuum base cracked, replaced both then water started turning green.
The pool store tested water:
FC : 2
A few days before water started turning green.
I bought HD test kit and that showed PH > 8. so added acid. And started slam and ordered K-2006 at same time. I started adding bleach blind, one gallon at a time, 2 times a day, water looks cloudy now.
Tested with K-2006 today,
FC : 20
PH: 8+ with acid demand 20 drops
CYA: 100+ (test stops at 100)
1. During SLAM is CYA test reliable? Should i forget the procedure and drain refill?
2. Should i correct PH now or during SLAM I should not worry about it?
Should i worry about phosphates, i know generally opinion here is not to, i have trees in backyard so leafs regularly fall into the pool.
Anything else i should do now?
Thank you for help
