So twice this year I have had yellow on my liner mostly on the slope areas. The first time my chlorine was low and I just figured Algae but I also has some work done around the pool with digging and the other thought was that maybe clay fell in. This is the color that it looks like. So I scrubbed increased the chlorine and my chlorine was holding steady and CC went to zero.
I then just went away for 4 days this weekend and came back tested water and had really high chlorine in the 10 because I filled my triclor generator and turned it up a little so I would not have to worry. Then today, two days later after testing we removed the cover and bam yellow in different location but on the slope again. Is this actually possibly algae with the high chlorine levels?
I also tested again.
Results:
8/9/2021
FC 10.6
CC 0
PH 7.4
8/11/2021 (automatic chlorinator turned down back to normal)
FC 9
CC 0
PH 7.4
CYA 40
Thoughts?
