HI - New guy here, with a 25k gallon pool in need of draining. (High CH and CYa). My estimate is that I need to drop it by 1/2.
I'm told it's dangerous to drain, and I understand why. But I don't need to go all the way down. The bottom will always be covered by at least 6" of water. Of course, I live in an area which is basically sand (near the ocean).
Do I need to hire professional? Can I do it myself? What is a pro doing that I couldn't do? I'm assuming they are not putting up scaffolding to support the walls, right?
