Hello. This is my first post here but have been reading threads over the past few weeks and found things to be very helpful. Pool was installed last year and I never had one before. So this is all new to me.
My pool was perfect last week. Had a party over the weekend and a big storm sun into Monday. My pool is now green. Pool store tested last week and was fine. Now they are telling me it is dangerous and phosphates are over 3800. Sold me $200 of chemicals and said I had to have someone come in and vac to waste. I don't know what this is. Is it something I can do?? Why does it seem like this is going to cost a fortune. Please help.
