Okay so my PH level is high. Never had that happen with my old pool. I went to get muriatic acid at Lowe's. When I grabbed a bottle it started spilling out the top onto their concrete floor and immediately started bubbling up and splashed my hands. Needless to say it burned and they had no water in the area so I had to run to the restroom while my hands were burning more and more. Anyway, I timid about using it now because I don't want to be burned and definitely do not want to spill it on my stamped concrete. Any advice regarding how to put it in the pool without those dangers? Hoping to hear from pros that have little tricks! Also, how do I know how much to put in there? I am sure it depends on how many gallons in the pool..but I am clueless here!
