I need to trim mine soon. I live in Corona but work in Orange near the circle. I wont be in work til Monday, but I'll be in Corona tomorrow through the weekend. Not sure how much you need, but I probably have at least a gallon bag or more.
Pretty neat video. I just moved my acan colony because my clowns were kicking sand all over it. Cool to see that the corals are able to dust themselves off on their own.
Thanks for posting.
