I may have just learned something, but I want to ask. I'm 62 and have been a do it your self'r since I was about 16. Started by taking care of a neighbor's pool while they were on vacation. The dad instructed me to pour the chlorine/bleach in the shallow end, walking back and forth the width of the pool. He wanted me to do this w/the pump off, I think. This way the chlorine would follow the curvature of the pool, drifting along the bottom of the pool, I guess in a way, placing a layer of chlorine along the bottom?
Was this perhaps the custom in the 60's? I knew to add the acid at the return line. Thanks.
