Not sure what was the cause but my pump decided go take a brief sabatical. I left it off for the night and I was going to quit fighting but something told me to add somemore bleach & try the pump this morning. I flipped thw switch & it started up. So I shall keep up my bleach assualt. If my cya is virtually nonexisitent will that cause my chlorine levels to drop quicker then if they were up around 20-30 ppm.
