Over the spring we have had tree frogs all over the sides and cover of the pool. When we took off the cover there was one in the wall inside and dh said it would find its way out. I don't think it did. Today I went to check levels for the first time and there was something in the skimmer basket. I thought wth is that and reached in and OMG. I just about yakked. There were 5 frogs in there, all swollen and gross. My husband isn't home and I didn't want my kids to see it so I got a coat hanger and pulled the basket out. Then I promptly put 3 jugs of bleach in the pool (I hadn't added anything to it yet and wasn't going to until I checked CYA but I can't stomach the thought of frog germs circulating in the pool-I read that they can carry salmonella) and turned on the pump/filter. So is this enough to not worry about if the water splashes in my face or something while I'm doing the checking? And for when the kids finally get in the pool when we get it all opened up? I admit I'm a germaphobe and easily freaked out.
