Good Evening,
Switched from Dichlor to bleach today given the information I received from reading the numerous posts related to the negative effects of CYA on the FCL.
Today took the initial measurement using Taylor FAS DPD kit , 1 PPM FCl, less than .5 CCl, AL, pH, CH within specs and CYA at 50 ( i was using dichlor for 2 1/2 weeks).
Pool math indicated to add 2.7 oz to bring FCL to 5 PPM. Added the liquid chlorine ( 10.3 % ) , circulated for 20 minutes with pumps in and then took reading 10 minutes later ....13 FCL with essentially zero CChl.
What have I done wrong?
Thank you
Sean
