Snail Overload?

[BradD_AP]

I have a 50 Gallon Reef that has been up and running about 5 months. Every night there are thousands of tiny snails all over the glass, live rock, and substrate. I have no idea where they came from. I just want to make sure that it's not something that will cause a problem. Thanks for the help

Probably just hitchhikers breeding. They will continue to increase in numbers as long as the food supply holds out, and then it will taper off. Unlikely to cause a problem, though.
