Ok, I have a 29 tall for D. Leucomelas that is empty and has been growing in for a few months. I plan to get my frogs after Christmas, so that the tank will have had about 3-4 months to grow in. When I stuck my head in the tank (don't worry, I won't do that when I put frogs in there, lol, might scare them a little) to watch my little gnat larvae crawl around in the water feature, i noticed my soil smelling just a little bit funky. Has it gone sour? Do I need to replant everything? Or will the funky smell go away? And is the funky smell harmful? Cuz if it's not, I'd kind of rather just live with it if the frogs can.
