I bought "Earthgro" potting soil. I had read several planted tank articles that mentioned the name and didn't realize they were talking about "top soil" sigh. The one I got is mostly "pine bark"..which I'm sure is not good. I was going to just dig my backyard up, but we live near the ocean, and it contains a lot of sand, and maybe even salt, I'm not sure...any ideas please? I'm getting discouraged and I haven't even started yet.
