Black spots

Recommended Posts

I noticed tiny black spots at the base of corals in my frags system. At first I thought they were tiny bugs, but after closer inspection I wonder if they're carbon dust or gfo. I was able to easily brush or blow them off and noticed more on the bottom of the tank. Anyone have experience with gfo coming into contact with coral Frags? How does it impact them? You can see how it kills the coral when it comes into contact.

I wonder if these little shards of carbon or GFO are being picked up by the powerheads and acting like flechettes, lacerating the tissue of these colonies. Maybe the tissue is retracting from the insults? Keep a close eye out for bacterial infections.

I use mesh filter bags on the output pipes of my GFO and carbon reactors to catch any stray pellets.  My sump used to be littered with shards until I added the filter bags.

I don't see how carbon would effect it.  GFO.. not sure.  It does have an infection though.  I would dunk in marine melafix or iodine.
