Okay I couldn't find a black plastic box, but will keep looking. So now my question is after I Duct tape the outside making it light proof, how full should I run it? I am guessing the bubbles bursting at the surface hitting the cuttings is what I am to try for. I am going to find that coral safe silicone glue to hold the stones and tubing in place then going to try it out. I also might make a bigger model I found on here that is more of an aero cloner but using pvc/sprayers etc but trying this out first.
