About a week and a half ago our pool turned green. It had been crystal clear all summer. I admit the kids went away to their dads for a two week vacation and I slacked on pool maintenance. I realize now that I let chlorine levels get too low for too long. Anyways back to the problem. After it turned green I brought a sample in to out local pool supply store and they tested it. Everything looked great except I had a ph of 8.2 low clacium and low chlorine. So that day I added 1/2 cup of ph lower, that night I shocked it and the next morning I added calcium...all as instucted by the store. They said my alkilinity was a little low but not to add to it that when I added fresh water to the pool it would be fine.
Nothing happened. The pool got a little less green less green but within a day was greener than ever. So a few days later I shocked it again with a super shock. And lowerd the ph again which at this point was around 7.8. The pool lightened a little and then back to green. So green I could see maybe 8-10 inches into the water. The whole time im doing all of this shocking the chlorine is just disappearing out of the water. I mean by the next day after the second shock chlorine wasnt even registering. So I call my pool guy at the store and he thinks there is a organic thing called cotton wood? In the sand filter so that night we open the sand filter but unlike what our pool guy says the sand is not hard on top. The next night we shocked it again.... Yeah I know.
What else can we do. The pool turns a lighter green by the next morning And in a hope that I can salvage the pool I go to the store and buy liquid chlorine (cause I dont want all the extra stuff that comes with shock) and dump about half a gallon of clorox in there. And every morning since then I have been adding a few cups just enough to keep the chlorine between 2-4 ppm.
Within about 5 hours of adding liquid chlorine the first time my pool was blue again. But extremely cloudy. Its been 3 days and now I can see about 18 inches into the water still pretty cloudy.
The ph has been at a steady 7.6 for the last 3 days. The alkilinity is up from adding fresh water. Stabalizer is good. Phosphorous good. The chlorine is still disappearing really fast from the pool and im having to constantly add it. Also still pretty cloudy.
is this normal?
Ive been backwashing a few timea a day. It is getting slowly better but is there something I am missing?
