I put together something as a trial run, but encountered a few problems.
What I did was I took an aquarium bowl, wove tubing around the rim, and put some tubing pieces in the weave with suction cups on the ends. Then I siliconed the weave to the rim and the cups to tiles. Sand on top of the tiles was enough to keep the globe down.
1. Burp - The first problem I encountered was the "burp" we discussed before, air being pushed out by the air stone I ran into the globe would come out in burps which disrupted the sand around the globe. I should have done something about this before setting it all up but I really wanted to get a feel for what it would all look like.
I am still trying to finalize how I will handle this in my head. I believe I will attempt to drill holes into the lip of the globe even though this isn't the smartest thing to do. The sand is a big issue, I have it on all sides of the globe except the entrance. I am tempted to instead incorporate the burp into the pvc pipe entrance I have been working on. I wouldn't mind the burp coming out of the entrance.
2. Entrance - For the entrance for my crayfish I have been working with some PVC pipe. It comes in several shapes and can easily be cut to length. I am thinking about using either a 45 or 90 degree elbow. I have been toying in my head with taking a strip of clear plastic 1" wide and the length of the circumference of the globe and wrapping it around the lip so that the globe continues down after the lip. I'd seal it with silicone. Then I would run the pipe through that plastic so that one end goes into the globe beach area and the other end is out in the aquarium jutting out of the sand. I have determined that the pipe needs to have a 1 & 1/2" circumference or about.
3. The Beach - Another problem I encountered was that the beach was difficult to manipulate. It is difficult for several reasons, i.e. not much room for my hand to get in, and the sand tends to want to level out and not allow a high beach. I am wondering if I should take a sheet of plastic, cut a circle out of it to the shape of the globe, cut a hole for the pvc pipe, then go ahead and put the sand in and silicone it to the globe interior. There's got to be a more simple answer on this one.
Any ideas or feedback is appreciated. Also would the best place for the air stone leading air in be at the top of the interior of the globe?
