I'm setting up a tank and was looking at the HD Play Sand. I've heard that people use them in their tank. How is it and how do you like it? I noticed there are some glass like piece in the sand and some other particles in the mix. Is it reef safe?
most say it's reef safe. i have used it in freshwater tanks in the past without issue. but it is kinda ugly....brownish....its just not the same as the snow white "reef" sand.
