Last fall I closed the pool the way I normally do with my chemistry the way I wanted it. Unfortunately, my wife decided to pump the water off the pool cover. She must have had the pump on a seam because she drained about 2 feet of water out of the pool. After more water accumulated on the cover (rain and snow) she pumped that water under the cover and into the pool.
I tested the water and my numbers are off. PH is 8.2+, Alk is 50, and Calcium is 130. It is this last number that concerns me because this is a plaster finish pool. Should I add calcium chloride now, or can I wait until I open the pool next month?
