Pipeline Fish Tank

This is a guy who is truly fan of fishes and aquariums. He made this awesome pipeline fish tank which is all over this caffe. You cat take a seat, relax and watch fishes how swims in those pipes. It is very unusual but you must give him a mark for creativity. Fishes can move from one aquarium to another because of those pipelines which connects them. Maybe because of that it is hard to fishes to find their way back in aquarium because fishes must eat too, am I right?

  1. Brilliant idea, however, would it not have been easier to just fill the whole thing with water, rather than having to worry about all these “physics oddities”? (I understand why it works, with the suction and all…)

  2. I suspect that this pipe system has a barrier somewhere in the middle of it. If it didn’t have a barrier the weight of the water above the 2 tanks would have to be PERFECTLY balanced (Not achievable in the real world) or all the water would run out one side or the other. The fish would be able to swim up into the pipe but not all the through to the other tank. With a barrier somewhere in the middle the pipe system would act like 2 inverted cups and you would get a nice illusion of “connected” tanks.

  3. How do you clean it?


  5. It’s pretty simple to setup … all you do is fill both tanks up seperatly, without the pipe. Then you fill the pipe on the ground, and put a cover on both end so when you turn it over it is still full and no water esacpes. then when you submerge both ends into the tanks you take the covers off. then its just a matter of having a pump between both tanks that can handly the amount of water between them and having the inlet in one tank and the outlet in the other tank.

  6. OK, but nobody seems to mention the issue of pumped air or disolved oxygen in the water, this is usually the problem of having air-tight filtration placed ‘over’ a tank because the air within the water collects at the highest point.

  7. It is so sad to see the dismal level of physics knowledge in the average person. Siphons? Pumps? Suction?

    Go to any store and get a piece of clear tubing. Fill a sink with water, hold the tube under water, then lift the middle as high as you want as long as both ends remain under water.

    Try a few other experiments. If the tube is long enough, you and use it as a level. Fill the tube almost full with water, then hold the ends far apart. No matter what, the water level at both ends will be the same level.

  8. Another theory on how they got the top part filled, would be via a vacuum port on the top of the unit. This would also solve the problem of removing any air pockets along the top.

    I was a bit worried about water movement (for purposes of aeration and filtration), but realized that the water would naturally move due to temperature differentials. The water warmed in the tanks, would rise to the highest point, and as it cools would return to the tanks.

  9. Another factor to consider is the weight. That much water would weigh quite a bit. Good to see they have it well supported.

  10. There has been plenty of explanation on how it works… I get it. But will someone please explain to me how in the world they got this up and running in the first place without flooding the restaurant!

  11. Stephen… every 33 feet of water depth equals an increase of 1 atmosphere of pressure (relative to sea level)

  12. I am not a physics major ( I will probably have to take a deficiency for grad school) but this got me thinking. I like the “start upside down” idea but would it also be possible to start right side up with water in each tank. Lower the pipe in and pump air out of the tube with a vacuum while you pump water in (both additional tubes coming from the bottom and going to the top of the pipe)? It might be easier or more difficult. Not sure.

  13. André Franquin, a belgium cartoonist, drawn that for his workless hero, Gaston Lagaffe, in the seventies ! Bubulle, Gaston’s red fish, wanted to see the world !!!

  14. attention scientists, why do people feel the need to describe something even if they don’t understand it. anyone who used the word “physics” in the above posts is ridiculous.

  15. Awesome!! How do you keep algae off the walls of the pipeline and how do you clean it?

    well you could take my penis and scrub the walls of the pipeline since it is friggin enormus!!!! hehe i dont really have that big of a penis but i wish

  17. I recant my “barrier” theory above and go with the simple syphon. That’s all it takes…

  18. My only question is how they change the water. We have to change the water in our tank every week or so, but it must be a tricky business since if the water in the tanks goes too low the water in the tubes prolly loses its suction.

  19. It’s a self-levelling system – if the level on one tank drops water flows through from the other side to fill it until they are at the same level. What I don’t understand is how they get dead fish out of the tube, because sooner or later it’ll happen and they will be floating up towards the top of the tube.

  20. Notice it’s self-sealing too. If the water level drops below the pipe, a few air bubbles go up the tube as water comes out, raising the water level in the tank, sealing the end of the pipe. There wouldn’t be a massive flood unless the pipe or tanks were damaged to where they couldn’t hold water.

  21. if i was to have 2 tanks, one on top of the other, is it possible for such a system to work?

  22. It’s called the Fish Highway and was built a LOOOOOOOONG time ago (like mid -90s)

    here is the link to the originator who even sells a book about it: http://www.fishighway.com/

  23. Only problem would be cleaning the pipes. Most fish tanks require cleaning as the algae starts to build on the glass.

  24. Whaha, that’s something i have been dreaming about!. Can you order this anywhere? 😀

  25. Oh my god I always wanted to make one of those for my dream house!
    Someone must’ve hacked my brain and stole the idea >_>

  26. Man, I just need that kind of Time and mOney… Would be cool if you can put some piranha’s in there

  27. Do they serve fish in that restaurant? Because it would suck to be a fish swimming around up there and look down and see people eating other fish.

  28. Ok, if you found the link to the fish highway that Morton posted….http://www.fishighway.com/ it has a FAQ section that answers all your questions.
    Here they are:

    What is a Fish Highway?
    Imagine a means for fish to swim out the top of your aquarium, up to the ceiling, across the room and then down into another tank. That’s a fish highway. Click here to see an illustration submitted in 1877 for the first one patented in the US. Today they’re made of acrylic plastic, the same material used for many custom built aquariums.

    Why doesn’t the water spill out of the highway?
    The highway tube is completely sealed except for the openings at each end which are submerged below the tank water levels. Like a large drinking straw, when the air is sucked out of the tube the water rises inside it and will stay there unless you let the air back in.

    Do the fish swim in it?
    Do the fish swim in it.

    Does it harm the fish?
    As the fish swim higher the pressure drops a little but it’s only slightly lower than the pressure pressure in the tank.

    How do you fill it?
    When the air is sucked out of the sealed tube the water from the tanks flows into it. Eventually, after all the air is removed the tube is filled with water.

    How do you clean it?
    Water flows through the highway continuously so the tank filters clean the water in the highway. Algea is removed using cleaning magnets for acrylic tanks.

    How does water flow through the highway?
    Water is pumped through a separate pipe from one tank to the other using a small pump. As the tank water levels change (one rises and the other falls) flow is induced through the highway by the force of gravity.

  29. its amazing because the fish is not bored and can actually see what’s going on in the house, i like this !

  30. these comments are boring. no i’m not into physics. yes i see how it works without having to read about it. the question i want answering is where is this? the place looks cool.

  31. So very cool

  32. well it’s pretty basic physics.. water (and all liquids) dont attentuate (expand under pressure) so as long as no holes are poked in the bridge the water will remain in there..

    also since it doesn’t attentuate there’s no resulting low pressure…

    water is an amazingly unique and interesting material in terms of physics… which is partially why it has it’s own dividion of the subject (hydrophysics)

  33. vovvv very interesting nice pictures nice main thanks

  34. thanks you

  35. thaks for all.. Good Job.

  36. thanks you

  37. I love it when people in blog post explain the same thing over and over again nice work jon

  38. how do you feed the fish??? wouldn’t air get into it causeing it to overflow?

  39. Cool pics, thanks!

    I like this. I also like how everyone turns into a “physics expert” to try and disprove this.

  41. nameless idiot says:

    take two glasses and a straw to connect a filled and a empty glass … now suck at straw … fill empty glass with liquid from filled glass … straw below waterline .. water stops flowing at same level … go figure yourself

  42. Looks like the water level in the bridge is a little low (pic 5). I would like to duplicate this, but I might keep it horizontal to make construction a bit easier. Also, it seems like the fish stay in the aquariums and don’t venture into the tubes a lot. Am I wrong?

  43. this is awesome!
    i was gonna build a custom fish tank for my home, but after seeing this i have new ideas.
    are there any instructions on the materials used?

  44. :mrgreen:pretty cool!!! how do you clean it?
