Hey Joe! Thanks for the reply! I broke down today and bought combat 60 to kill them. We have so many, we don't even want to get in. The pool guy said that it would do the job but after reading the bottle it looks like it is to help with preventing algae. This is also our first year with the pool and our neighbor said the same thing you said about having them bad the the first year they had their pool. Anyways hope this does the job! Thanks again for your reply!
