Don't mess with dyes, no idea what chemicals you may be putting in the tank. I've made LR in the past, you need to do 6-8 weeks of freshwater curing, then put in saltwater with a frozen shrimp or two, wait another 4-6 weeks and put it in the main tank. It will take a few months for the coralline to migrate to the rock, but after 6 mos. it will look like a piece of Fuji. Make sure you have at least 2-3 watts per gallon in the display, and scrape a little of the coralline (you must have some good LR in the tank to seed the homemade LR) with a razor blade every few days, it will grow my friend!
