Thanks, more good info!
I have a saltwater tank, so no problem with checking specific gravity.
I was kinda planing on having some of the return water from the filter flow over the terrain (driftwood root terraces) just to keep everything wet. Any suggestions on what kind of mud would be best? I live in Tennessee near a small lake. So would lake sediment work? We also have a lot of clay type soils. Not so much brackish marsh land nearby. I'm guessing it would be best to sterilize it some how? Have changed my plans to include more land area now than what I had originally thought. Haven't thought of a way to create a tidal effect in a tank though. Do you do this some how?
I had read about them being Houdini's & planed on a lid. Hadn't thought about air temp though. Will have to watch that when I get this set up.
What kinds of food do you feed and or raise? When you say bio slime, not sure exactly what you are referring to? I was thinking small earthworms & bugs like for reptiles.
Thanks again for sharing your experiences. If you have any more info or links, all would be appreciated.
