I'm setting up my new 210 gallon tank. The inhabitants will be a violet goby, bumblebee gobies, and eventually maybe an Indian mudskipper or two. Because violet gobies require a soft substrate, preferably one in which they can burrow, I would like for it to be sand. My violet goby's current tank has black (moon I think) sand. This sand works fine, but the goby can't burrow in it. More of it would cost money too. So, I'd like to use a fine sand that I found in the creek (heavily eroded ditch) next to my house. My first concern is that it might contain harmful organisms, and that it might make the water too cloudy. I would think that the marine salt would kill a lot of the organisms (brackish tank).
Can someone tell me what I need to do to this to make sure it's safe?
