Open Bottom Aquarium
 

Hello. I am in the works right now of building an open bottom aquarium for myself or possibly for sale. Is there anyone that has experience or interest in these concept tanks?

Won't the water fall out?

no it gets trapped in there. Once the tank is displaced with water it will stay there unless something can take its place. Being that the tank is a sealed chamber it stays suspended in the tank. Its the same science behind the old upside down cup in the kitchen sink. Fill the sink and turn a cup sideways till it is full of water. Then turn it upside down and pull the cup. Presto the water is suspended in the glass. Same idea here.

Do you have any links or pics of this idea? I

I dont displace the tank that way though obviously. Be a lot of weight. Ive seen people use an air hose and suck the air out while water in the lower tank replaces the air. I have a special pump to do it though. Ive had a quick set up going for a month now. I just wanted to try this idea out before I ordered the glass for the upper tank. The lower tank and cabinet have been built already

Wouldn't fish swimming out the bottom. Or how do you suspend rock and coral

I've seen this before but don't think it'll work we'll with saltwater. You won't be able to run a sump or skimmer. The bottom tank is gonna be too shallow for a hang in back skimmer

Plus you'll need a very accurate ato top off. If air gets into the top tank you'll have a major flood

Seems like an interesting concept, the only thing I'm confused about is how you would remove the air pocket?

Simple as sticking airline tubing up there and sucking?

yes they would swim in and out of the bottom and as for coral you can just build up your rock if you like. I see it being set up as an all fish aquarium though. Right now I have some live rock and coral in my set up but you dont really see it until you look down the upper tank. It is a very unusual look in person. Its almost like there is another dimension to the tank. Dont really know how to explain that part of it
