I have bought out all of the large bleach at local Walmart and the next closest and am down to my last 4 jugs as I am trying to clean up after an algae bloom. I shocked it yesterday and have been adding 7 jugs of 182 oz bleach (36,000 gallons pool) every 30 mins this afternoon and have done 6 doses. Each time I check the chlorine level it is 0. my CYA is ~45 - 50.
I checked for CC the last time and it turned dark yellow when I put the R-0003 reagent in. I also checked for FC after adding the last chlorine dose and it didn't show any level.
Could my testing agents have gone bad in the past month?
Any ideas or suggestions?
Also, the pool is very clear and no noticable green and hardly any grey.
