I have a 40K gallon in ground pool and am in the process of starting it up for the season. Emptied one skimmer basket, no problem. Went to empty the other one and a large bull frog jumped out and almost caused a mess. Totally unexpected. My 8 year old boy keeps telling me "Dad, you've got to get all those frogs out of the pool!" I don't know if he will go back in the pool now that he has seen all the frogs and tadpoles..
