Case in point had a new client several years back brand new pool turned green. He called me for help and ran the full gamma of levels and came up with the game plan to slam. While slamming he turns back on his expensive ozone system that I warned him against using, "BUT I SPENT $2.5K ON IT"
and the slam isn't progressing. I disconnected the power to it and completed the slam. Now all is perfect and decided to use LC and stay on the hot side for a bid to be sure we're in control. Then he starts with this rant "oh chlorine to high, must be lower..." I ended up installing the RJ60 and uninstaled the ozone. Then I walked away when I caught him funkying around with the chemistry between visits sending me in circles. Thank you but NO thank you. If you know pool maintenance then you don't need me and I wouldn't want your money, Done.
