Not sure what this is

[hawkinsrgk]

Hello Everybody

Can you tell me what this is on the overflow?

There are hundreds of these in the tank. Not sure how big of a problem this is or if it is a problem.

Thanks
Randy

I can't really tell but I believe Tyler is right. Harmless filter feeders that need clean water, so it's a good thing.
