Great looking rock. I am going to try and get some local club members together to try it here in Nashville. There is a very good thread on how to cure this stuff, and vinegar was used to help speed up the process. As I recall, once you feel the rock is cured, you want to allow the rock to sit at least two more days, with no water changes, no movement at all. If the ph is still ok, then you are good to go. What kind of dye did you use? I realize it was Rit, but is that the standard fabric dye, or did you use the cement dye?
The shapes are great, and I like the idea of the cup holders for future frags, very inventive. As I have a 500 gallon to fill, I have a lot to create, but it will be worth not taking it out of the ocean.
Keep up the great work.
