I need some opinions on this stuff as far as being used as a substrate. I have heard a lot of mixed reviews about it. Some on here seem to like it and use it and some say that it's not good on the skin of a BP. Which it is anyway? I would use it if I get a majority of people telling me that it's safe for a BP because I do have some I could put in my tank. Anyway, what do you guys think? Thanks!
