Thanks, I feel better now.

It's the "acid demand" test to be done after you add the 5 drops of R-0004 & get the pH color. It says to add R-0005 dropwise & count - compare with color standards until desired pH is matched. See treatment tables to continue.

It took 5 drops until it was in the 7.5 range. I can't find a "treatment table" anywhere, so I wouldn't know what to do. I'm glad I don't have to worry about it until we are through dealing with the chlorine.

Ya know, the pool store had me add a whole bag of "stabilizer" about 2 weeks ago. Is that why my CYA is so high & causing me all of these problems?!
