I noticed something interesting. Our neighbor behind us has a bee hive in the wall of their house
We have a saltwater pool and the bees were inundating our newly filled pool to a point that you wouldn't want to get in. The salt didn't bother them. I waited a couple of days to go get some CYA, but I did notice that once the cya was added, the bees quit coming to it.
Just an interesting tidbit.
