Re: Swimming pool?
Welcome to Beesource!
No one can give you assurance that your bees will not find your pool water attractive. There is some reason to believe that pool water is attractive to bees because it has a distinctive smell, i.e., that imparted by the chlorine.
So if you want the bees to use an alternative water sources, make sure it is easy for bees to access (perhaps wood scraps as floats to land on, rocks, rope, etc) and also has an attractive smell. You may have to experiment as to smell. Chlorinated water (pool water) may work, or water with compost material (as in an artificial swamp) may work.
It will probably be best to get the bees using your alternative water sources before you set up the pool. If you wait til the pool is set up, it will likely be more difficult to wean them off the pool water.
