Why does pool school say to test CH weekly? I thought it stayed the same unless you add water.
After a couple days of mixing in the rain, my ch is now 310, down from 350.
It means that calium-rich water was replaced by calcium-free rainwater and/or the pool level went up with the rain, diluting it.TomAtlanta said:After a couple days of mixing in the rain, my ch is now 310, down from 350.
I don't understand how this works. Does that mean that over 10% of the pool water was replaced by rain, or does it mean that the calcium is somehow removed from the water, or does it mean something else that I don't understand?
