Hi, it's nice to know I am not the only newbie. What made you decide to use sand as a substrate? Are you going to have fish in the tank? Have you heard or read about the "dirted " tank? I read about and have seen people on YouTube using miracle gro as a substrate capped with gravel. I'm thinking of toying around with it on a spare tank, I'm kinda scared tho'. I am quite sure I will end up with a soupy mess!
