I'll know exactly later this evening. FAS-DPD kit came this morning.![]()
I'm gonna go with 30 too. First thing I learned from Ben and you guys is know your CYA. I figure I'll be able to use up about 20 oz's of old Dichlor to bump it up ten. It takes 1.8 ozs of Dichlor to raise chlorine in my pool 1 ppm. Am I right in assuming that Dichlor has a 10 to 9 ratio of chlorine to cya?
