I just got back after a little over a month to find the bottom of my pool green. I have not tested the water yeet but will do so after the sun comes up and will post results. I know the water was neglected and hope this will be an easy recovery. Is there any quick fix to kill the green and get the pool back to the pretty blue I had before? The pool is an 18 X 4 above ground with a swg. I am hoping that scubbing and soe technical support from you all will get me back on the right road.
