My fresh water source is already very high level of cya around 100 and high TA around 120. The water is extremely hard. Cya in pool after 1 day over>200 ph 8.4, free chlorine very low, total chlorine 0. What shall I do? Please help me as I have been absolutely crazy looking to balance my pool, which seems impossible. I have only a small 10ft pool, but cannot exchange the water I filled just yesterday night.
