I put 3 gallons in to slam. Checked the water it showed no chlorine. but the water was clearing up. I put one more gallon in and kept in running all night. It was getting clearer. But my test still showed no chlorine. I put in 5 more gallons. Tested in a few hours. Still no chlorine in pool. The pool is just a little bit cloudy. So the bleach was doing something. Maybe old chlorine? So I went to another store that sells liquid pool shock. Its called Austin pool tech shock. Made in usa. active ingredient sodium hypochlorite. Has anybody used this shock before? It says to add one bottle to every 10,000 gallons of water. This is the first time this every happened. Help please. Filix.
