I've looked at a lot of coral pics on RC, and a lot of the corals have outrageous colors and are being sold at outrages prices. What I finally realized is the owners of those corals have purple substrate (or purple eggcrate or purple frag plugs). Obviously the substrate contributes color to the corals ?
Where can I buy purple substrate so my corals are brightly colored and I can ask obscene prices for tiny frags?
