Due to all the rain we have been getting my CYA is somewhere between 20-30 I think (black dot didn’t quite disappear when view tube was full at 30ppm). I need to add CYA but was planning to chlorinate with trichlor tabs for a 5-6 day trip I am taking in 2-3 weeks. Using pool math it looks like if I used 5 - 8oz tabs during my trip my CYA would rise about 16ppm. I’m thinking this would put me around 40ppm. Should I add 1-2 pounds of CYA in the next couple days before my trip or just plan to keep up with the chlorine losses until after my trip, retest and go from there? Thanks for the help.
