I like the looks and texture of onyx sand, I've done 2 tanks now, a 20 with 3 bags and a 38 with 4 bags. It's so easy to work with and holds plants real well, I guess something that seems so good, I should be real happy. The buffering is my only complaint, the description says a slight buffering effect, I test my Kh at 6, and my Gh at 10 in a non onyx tank. With the onyx it has a Kh of 8 and a Gh of 13. Way more than I expected, my plants don't like it either. So, how long will the buffering last? What does 'over time' mean? 6 months, a year or 2? I've got 5 more bags on the floor ready to redo my 55g tank, now I'm not sure.
