I had been using Trichor tablets with an automatic Chlorinator and Cal-Hypo to shock. The water was slightly cloudy and shocking didn't seem to help. CYA was 130 ppm, after reading some info at this site I decided to try switching to bleach. I drained about 66% of the water from the pool and refilled to reduce the CYA level. Since then other than Clorox Bleach, the only thing I've put in the pool was 25 lbs of calcium chloride dihydrate.
The water is now clear. I've been adding 1 gallon of regular Clorox bleach each evening, which the pool calculator indicates will raise the Chlorine level about 3 ppm. When I test the water (before adding bleach) the next evening, the FAS/DPD test has been indicating FC=2 (+/- 0.5 ), CC=0, a little below the minimum listed in the Chlorine / CYA chart.
1. Is it normal to loose about 3 ppm Chlorine each day? Does this indicate I need to "Shock", or just need to add a litte more bleach each day?
2. It has been sunny, and the pool is in direct sunlight most of the day. For this location (south east Texas), would it take more or less bleach per day if I raise the CYA level and then maintain the higher Chlorine levels recommended by the Chrorine / CYA Chart?
Thanks for your help and this site.
