CH has increased over time to 415. At what point do i need to drain a little and add new fill? Water is very expensive where i live. I'm guessing the calcium came from the city water since i only use liq chlorine, acid, backing soda.
from pool school; A plaster pool should have CH levels between 250 and 350 if possible. You lower calcium by replacing water or using a reverse osmosis water treatment.
