Thanks for the link to the ABG soil. I'm going to Europe now but I'll order it when I get back. I'm going to keep the eco earth until it's time to replace it. I just hate wasting.

I'll see how the Zoomed moss is doing when I get back in two weeks before I decide what to do with it.

For drainage, I have one inch of gravel under the eco earth. When I set up the tank, I didn't know I had to separate the gravel and soil, so they're mixing a little. But when the time comes to replace the soil, I'll put a screen between them.
