until this year. CYA is so low that I can still see the dot easily even with a full tube. The water in the comparator is mildly milky when the tube is full. Water is clear in the pool and SLAM is done. However, we are going to use the pool this weekend. I am using pucks to raise the CYA, but i want to know what range of FC I should be in assuming a 0-10 CYA level...
A few years ago (4) my CYA was so high that the dot disappeared with just a few drops. It has taken that long to get it down without resorting to drastic measures.
