There have been a few times recently that when I add bleach, it seems to bubble up to the top of the water and float around the pool. Usually when I pour it in, it goes straight down and is pushed away by the returns and never bubbles up.
Could this be a sign of bad bleach? The only reason I ask is last time it did this, I had an unusual amount of FC loss. I have checked for OCLT and pass with flying colors so it is not that.
