7070 gal AG pool filled w well water; added bioguard smartshock(dichlor) 1lb last 4 days. Using Taylor K-1000 & K-2006 test kits.
The lowest reading for CYA in K-2006 test kit is 30ppm. I have not reached the minimum 30ppm level. I am not sure how to check CYA lower than the 30ppm, & also do not know if/or how much CYA to add?
Thanks for any advice!
