I have been chlorinating with Trichlor pucks in a rainbow automatic chlorinator. I recently tested by CYA and it is at about 80. I do not want to increase my CYA, so I have looked into Cal-hypo pucks as a replacement option. I shock with granular Cal-hypo and my calcium level is about 400. I am seeking advice on the best way to chlorinate my pool on a daily basis. Please advise.
