I put the suggested amount (actually a bit less) in some socks and let it dissolve. A couple days later I tested CYA and it was double the amount I intended - I was going for 30 and it reads 60. Now I know that the general advice here is to wait a week, but I figured if you tested early it would show up lower than your target, not higher. CYA was 0 when I opened. Pool calc said add 4 lbs 6 oz of stabilizer to bring CYA from 0 to 30. I added a little less than 4 lbs because it's all I had. Water is crystal clear but I'll need to do the vitamin C in a sock and rub the stains off the side. Here are my latest test results:
FC - 18
TC - 18
pH - 7.4
TA - 90
CA - 50
CYA - 60
So my question is - Could testing too soon after the CYA is dissolved cause higher readings? I tested water from two areas of the pool. Pump is running 24 hrs/day during start up. Thanks!
