Hello, my names Andrew. My cousin over the weekend was showing me some kind of little air bubble thing he could purchase for his tank. He likes to keep crabs, but he wants to have fish too. So it creates a little air pocket for the crabs to live in.
I liked the idea, but all the ones he showed me were very small.
Anywho, i work with solidworks at my job where we design aquarium pumps and filtration so at lunch i modeled this up quickly.
I have an extra 37 Gallon Tank sitting around and thought i could do this.
Please excuse my poorly drawn rocks.
As you can see below, the air pump will just slowly fill the section to the left with air, displacing the water. So when its all the way filled there would be a large section for crabs and what not to hang out at.
There is an access panel that will be held in by small screws and a gasket. This way you can set up the area in the bubble before you fill it with water. Or in case something dies, you can remove it. Unfortunately you will need to drain the tank to do major surgery.
Since the Co2 is heavier than the Oxygen i believe that the old air will be forced out thru the bottom where the air is being pumped in.
Im thinking some clear acrylic for the center divider, and if im correct with my maths the force up lifting because of the air should be less than 47lbs pushing up on the acrylic. I just plan on using silicone to hold it in place.
What do you guys think?
Stupid, interesting, neat?
Thanks,
Andrew
