Central Valley SWCG w/ Low CL & High PH...

Janet,

Thanks again. With your help and the help of this forum I've made some good progress. TA is down to an acceptable level and shocking for several days killed most of the algae. Its been about two weeks since I shocked so I need to stir it up and make sure the algae is actually under control.

The pool is a pebble tech gunite finish. Can you walk me through addressing the hardness level to protect the finish of the pool?

Also, once I get the calcium level in check can I reduce the use of the pool pump. What other considerations do I need to keep in mind for the winter? Outside temps are 60-70F during the day and 40-50F at night, sometimes lower. The water temp is presently 45-50F now.

Thanks as always!

I'm pretty sure that Ca should be 200-400 for your pool, but I'm sure someone will correct me if I'm wrong. I gather you're not swimming--I usually cut my pump runtime to 3-4 hours a day during thexwinter, and run it overnite if air temps are supposed to be 29 or lower (only happens a handfull of times during La winters, thankfully!!). Do you plan to close the pool or keep it open for the winter?
