Late winter tweak?

[zelmo]

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?

If you have a way to circulate the water now, I would go ahead and get the calcium up. I have no experience with plaster pools, but it seems to me that any amount of time spent with the calcium at a level that causes leaching is too much time.

You can use the pump your wife used to drain the cover to supply the circulation. Get a good flow/ circulation going with the pump and slowly add whichever chem you'd like into the stream and let the pump run for a few hours. You would have to put the pump in the pool, which would neccesitate pulling a portion of the cover back, but then you would have the water flowing so that chem additions could be done
