Question Biosphere underwater? This product puts dry land in your tank

Hey guys, thought I would strike up a discussion about this piece of equipment I found.

http://www.aqua-life.ca/Under-Water-Biosphere.page

Several sizes and its interesting to see the aquarium inhabitants using it, namely a newt, which I have been pondering keeping, but at the juvy stage they spend a lot of time on land (fire-belly). Anyone have thoughts or experience with this?

How ingenious.. I've always had the problem of choosing between a full tank and fiddler crabs... and it's not even expensive. I wonder if the inventor thought of it while watching spongebob. thanks for the link! If anyone tries it please come back and review it!

EDIT: oops. I didn't realize those prices were outdated or in canadian dollars or something. I tried to look for a place to buy and the underwater island is more like $30.

You keep the airline hooked up for fresh air?

cool idea either way, I did something vaguely similar once with an inverted 10 gallon(maybe 5) inside a 55 gallon tank. had to weigh it down with a big rock though or it would float.

I've seen these before and I really like the idea. I haven't used one yet, but I have been playing around with the idea of building one myself. The idea seems simple enough and there are some tutorials online that make it look pretty easy.

Haha it's funny I thought more people would have heard of these! Love sharing new ideas! The fiddled crab and newt possibilities are nagging at me!

Wouldn't the air pocket in there get depleted of O2 after some time? Not sure how fast it will equalize with the water.

Yeah, interesting concept, but without an airline in there to continuously (or at least periodically) freshen the air, eventually the air will get stale as all the oxygen is breathed out.

I've been meaning to make myself something like this for years... and here I thought I was being original, lol

For those that didn't read the website linked:
"Simply connect an airline to the Biosphere, watch the water get pushed out, and create a dry environment with a water access to the rest of the aquarium."

Yeah, saw that, but I'm not sure whether you're supposed to leave it connected full time once the water is pushed out. I don't see a stream of bubbles anywhere in the photos, do you?

If you watch the video the site puts up it shows bubbles occasionally escaping from the biodome. I think for aesthetics they hide the line in all photos and video but I figured it was necessary to make it work
