Long story short... My Tang does not have, and will not have "Hole In The Head" (HLLE) due to running carbon.

The skimmer that I was running was the "DFC-180 Controllable In-Sump Protein Skimmer - Aquamaxx" which is not even coming up on BRS anymore. Probably a good reason. Nyos for the win IMO.

Now to find out what is causing the lack of color in the corals.
