Black Mold on Top of Hydroton

I noticed today that I have what appears to be a little black slimy mold looking residue on top of the hydroton in my General Hydroponics Water Farm pots. It is the area directly under the drip rings... I turned up my fan assuming I need more air flow. I have two small clip fans now but will add two more for more circulation. I'm now concerned and not sure what to do next...

How do I get rid of what appears to be a black slimy mold? The last thing I want to do is pull cuttings off this...
