I am testing with OTO.

Yes I too think the pool has a very high chlorine demand especially after the algecide. I will continue to add the bleach. Good thing I stocked up today!

I added the Muriatic acid and a tested a few hours later. PH is lower and chlorine with WAY high! BRAVO!

Question: Since I can't see the bottom should I still vacuum? Should I scrub the bottom? I scrubbed the bottom today and it turned green again, not as bad of a green but still green. Does this mean there is still live algea at the bottom? Also, should the high chlorine levels kill the algea off?

Thank You!
