For me, its one one piece of equipment that could cost me a lot in trouble down the road. Its easy enough for me to go to my mom's every day or 3 and dump in the bleach. If I were going to build my own in IG pool someday, another thing I would NOT do is pour concrete around it. Eventually you're gonna have to dig up those lines and do work. Grass with some nice slate or river rocks around the perimeter is a hell of a lot more forgiving. Less is always more in my opinion . . .
