A few questions about "dirt" tank and DSM
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!
