So to date, i've added 4lbs of stabilizer to my 15,000 gallon pool.
Added 2lbs at first, then the 3rd lb about 4 days later, then the last lb last Wednesday.
So its been exactly 1 week since the last pound was added, a week and a half since the pound before that and a little over 2 weeks from the first 2lb. This is a new fill and I had a CYA of 0 when I started.
I tested CYA tonight and at 20 the dot is completely blurred out. At 25, I can barely make out the dot, and at 30 I can see it pretty well.
For adding 4lbs of CYA, I'm only getting a reading of 20-25. That doesnt seem right to me. And i'm using about 3-4 ppm FC every day....Even with the solar cover on all day.
FC tonight was 3.5, CC was 0, PH 7.5
I added 60oz of 12.5%. Which should bring me close to 8 on my FC. I'll wait 45 min and go back and test. I've constantly loss less than 1ppm every night and the pool is CRYSTAL clear.
The CYA is confusing me though...
