This summer I have been fighting a green pool. Currently my chlorine is @ 13 for free chlorine, my ph is 7.4, alkilinity is 120, CYA is 150.
First there were only small amounts of green on the pool floor, then the pump motor went out and it was 3 days before i got it back up and running, now completely green and cant get it to clear up. Tried shocking it and using algae 60, brushed all walls and floor of pool, and running on filter for 48 hours with no change. I was told I probably have mustard algae so I added algae all and brushed again and still running filter now running 48+ hours with no change. What do you suggest?
