Thank you for the replies. I went ahead and shocked last evening. I thought the water was a bit cloudy, no algae, and I'd read (not here) that shocking should be done once a week. After posting, THEN reading, I see that's not really the case.

I had purchased a drop type test kit but couldn't read free chlorine (nor could my wife) so maybe there's a difference in kits. I am using strips until I find a good kit.

My pool is a pebble tech with DE filtration and a variable Haywood pump. I also have a solar heater.

Another question: If chlorine tabs have stabilizer does the stabilizer always stay in the pool? It seems that the chlorine levels took most all day to go down today.


Thanks again.
