I just drained and refilled my pool. I have the taylor test kit but couldn't get a reading for CYA and FC. Am I to assume there is no CYA and FC? Just wanted to be sure before I add the CYA.
I added about one gallon of muriatic acid to lower the pH and TA last night. I need to go get more chemicals...muriatic acid, cya, liquid chlorine. What should I get for raising CH?
