Thanks to all for your opinions, BUT......
What about the dead worms that have been removed throughout the winter and how about the bird poop that ends up on the mesh cover and then it rains and migrates into the pool????

Seems like this isn't much different than having a "solid" accident from a child which most of you have stated in the past-----"SHOCK, SHOCK, SHOCK, Better safe than sorry". "Kill the bacteria"!! Somehow I fail to see the difference.
