Liquid Chlorine question regarding Algae

[copotay]

I use Pool Essentials liquid chlorine with 10% but also read that the liquid chlorine degrades quickly in the bottle. My date on the bottles are Feb of 2024 and stored out of sunlight in a pool shed under a tree with average temp of 80-90 degrees. Does anyone think it is possible that although the FC test with Taylor test kit shows proper FC range for shock, that the chlorine has degraded enough to not be effective although the test shows the correct amount? Thanks

The degradation you speak of means the chlorine gets less concentrated, so you get a smaller ppm increase when you add it. What you measure in your water is what you have in your water, doesn't matter where it came from.
