Carbon causes Helle - damn guess all the fishes swimmin in R/O water are doomed. Try excessive dissolved organic carbon not activated carbon 2 completely different things.
I wouldn't use GFO, Chem Pure or Carbon during cycling or even for a few months after. GFO is for PO4, Carbon for toxins emitted by Soft corals and Anemone's also TDS , Chem pure elite is for Nitrate, Po4, and Silicates. This stuff is for my Reef.
