Off the Chart Cyanuric Acid

[BigDave]

... 1/4 c pool water and 3/4 distilled water. From that one cup I took a sample and my reading came in at 35(x3)= 105. That's dramatically lower than the "off the charts" I was getting. Did I do that correctly? ...

Bringing bad news - Sorry!
Diluting 1/4C pool water with 3/4C distilled, we need to multiply by 4. The pool water is a quarter of the volume we're testing. The result is CYA = 35(x4) = 140. Sorry.

It's OK to run the pool with CYA that high, just need to keep FC high enough.

I though it should have been x4..... Oh well. Now I I have misread my ph and adjusted it too high. It's at least 8. Guess I need to add music acid to bring it down? A small amount is what I have read.
