Why is my 15k gallon inground pool using up some much chlorine? It seems like every 3 to 4 days the pools starts to get a light yellow tint on the walls. I brush, vac and add 1.5 gls of 10% liquid bleach and it clears up. it reappears again in 3 to 4 days, is that normal? A TF-100 kit is arriving tomorrow to better understand the chemistry.
