hi, i'm new here. I have an 18X36 inground pool with a sand filter that has not been open for 2 summers. The water is green and cloudy with a green and brown color visibility is zero. I'm getting ready to open it on april 1st. I walked out today to the deep end of the pool and stuck my aqua chem test strip out there elbow deep and got these results
Tot chlorine 0
Free chlorine 0
Tot alk 180
Does anyone have any idea how I should start?
I don't want to waste all this shock and bleach I have.
