Upside Down Aquarium

[KenR60]

Here is an idea for other Pond Owners who would like to see their Fish like in an Aquarium.

Its called an "Upside Down Aquarium" and as it says, its upside down so the Bottom is the top and the fish can swim up into the tank above the water surface. I made this one to test the Idea and will replace this one soon with a 2.4metre one thats built around the Decking so that it looks part of the Design.

The first picture was taken within 10 min of adding it to the pond and since adding it I've seen some fish I didn't know I had as well as others I haven't seen for months.

now that is awesome!

What a neat idea! I wonder if my Koi fish would swim up to investigate the upturned tank though. They're very shy and the only way of seeing them is to stand well back and play statues. As soon as you move they swim for cover.

All the algie growth...no! thats what I'd be curious to see after a few week.

Thanks Cazador,

Dave, odd that your Koi are so scared? Try feeding them everytime you walk out there and soon they will recognise that seeing a people means FOOD ... LOL ... Being similar to Goldfish they'll soon remember. As soon as they hear me open the sliding Door my 70 Goldfish all gather in the one area and they follow me where ever I walk. Even the Hundreds of Natives ( Rainbows ) were very scared like that once and I hardly ever saw them, now they too gather in large schools waiting for the food to drop.

All the Fish enjoy the Cube, thats why the Next one under Construction now is 2.4 metres in Length so that we can sit back and watch them either in the Pond or in the Tank. Of cause the Water needs to be nice and clear which I seem to always have.

POC3442, Yes depending where you have the Tank Algae can be a Problem, the next version has a 30degree angle on the Top so that the Decking will continue up over the Tank so that it looks like it was built into the Decking, I'll have sections cut out to allow Light but thinking of using some kind of Blind System to give shade in Summer but left off in Winter to generate heat. I intend adding one of the Heavy Duty Magnets to the Front for Cleaning. At the moment the Cube is 4 weeks old and gets Sun daily, yes its got a nice coat of Algae but not like an indoor Aquarium that you try and keep perfectly clean its not something that I'll clean when I can't see the fish. The Algae gives it a more natural look when in a Pond.

Night Time Viewing is good too if you throw lights towards it, the Next Model I intend lighting it from the Top so I'll build in the Lighting so that its out of sight. Planing on using the 12mm Round Neon Tubes that they use to lightup under Cars. This way its easy to hide and I'll use 2 or 3 different Colours so that I can change the effect.

The whole Idea of the Deck/Pond/Aquaponic System was to have it looking just as good at night so that we could enjoy it anytime.

If and when i get to Qld thats one system i would like to see

[gooseraiser]

Stupid question...... how do you keep the water in it?

[bunya boy]

Gooseraiser,
Simplistically, fill your Kitchen sink with water, put a drinking glass under water, tip it so it fills completely under the surface. Rotate the glass so that the top opening is at the bottom and raise the whole glass up, keeping the opening under water. The air pressure (at sea level) will suport a column of water 32 feet (10000mm) high with a vacuum at the top.
That's how it stays there.
Air (Atmospheric) pressure will support a column of Mercury 1000mm (32") high, which is why until recently, Barometric pressure was measured in mm or inches of Mercury!!
Physics lessons, I love it!

Cheers IanK.

Well that makes me feel stupid..... but at least I learned something
thanks for that. I appreciate it.
