We went away for 8 days on vacation. I put tons of shock in the pool. Came home to a green pool. The chlorine level is high and all other levels look fine. Any suggestions. I have an above ground pool 15,000 gallons. Family coming in 3 days HELP!!
CL is at 3ppm
alk is at 120
ph is at 7.6
I used test strips to get these numbers
