Richard,
thanks for the reply. Yes, it is a cartridge filter here in Arizona. I am goung to fill out and post the pool calculator results later today. I went to a pool supply store with a sample and was told that my chlorine was .5, ph was 7.8, and alkalinity was 200 and there was no stabilizer at all. They advised to drain the pool and refill it in November because of the extreme summer heat here. I purchased a new complete test strips kit and tested the water. Surprisingly, the stability showed to be safe. I'm not sure if sombody elses pool water sample was being used.
