A few questions about "dirt" tank and DSM

Hi all,

I'm planning my first non-inert substrate tank soon, and it will be a 20L low tech (for now) tank. I already have a bag of MGOCPM, so I think I will just go with that rather than going through the pains of making MTS or anything. I plan to cap with sand. Here are some pretty simple questions I have:

1) I plan to cap with either tahitian moon sand or PFS. I heard that a 1" cap is enough, but how much potting mix should I have under it?

2) I plan to dry start this tank with DHG belem. How do you think it will do in a non-CO2 tank?

3) Is dry start as simple as filling with water to just under the substrate level and then keeping the tank covered to keep humidity in while running the lights for the normal photoperiod?

4) I plan to have manzy driftwood in the tank too. Are there concerns with the substrate under the driftwood causing problems because it can't burp out its gasses?

Feel free to comment/answer any or all of the questions (or none!). Thanks a lot for the help!

I think the 1" cap is a good idea with sand I wouldn't do any more than that. As far as underneath I would do 1-1.5 inches.

2) I plan to dry start this tank with DHG belem. How do you think it will do in a non-CO2 tank?

What are your plans for lighting and fertilization?

3) Is dry start as simple as filling with water to just under the substrate level and then keeping the tank covered to keep humidity in while running the lights for the normal photoperiod?

You will also want to do frequent misting with DHG unless you can seal the tank enough to keep the humidity very high

4) I plan to have manzy driftwood in the tank too. Are there concerns with the substrate under the driftwood causing problems because it can't burp out its gasses?

I would put the manzy in first and then the substrate so that it doesnt shift around.
