could you send me some plans for some aquarium i am looking for a 75 or 80 gallon woodworm18@yahoo.com thank you so much

I realize this is an old thread, but i was wondering if it gets enough water circulation to keep it clean after its been set up for a while now...if its still set up.

I too would like to know if this is still up and running

Jim

hey, I almost forgot about this... I agree with the last couple posts, how is it running so far? Got any new pics?

Good idea is it still around?

You don't really need a pump for this to work. Take a clear plastic cup and submerge it in your tank so that it is completely full of water(no bubbles etc). Now begin to pull it out with the bottom facing up. You can keep pulling with the water still inside until the rim of the cup reaches the water line. So it is much simpler than you think. =)

Now you just have to have a deep enough tank to submerge another tank completely in it. =). Would be a neat idea for a pond. With random tanks sticking up so fish can come out and you can see them.

Has anyone had a flood yet? This works just like a siphon and if the siphon breaks the water will escape. The fish highway guys have documented some big floods.

The guy in Singapore looks like he left enough head room in his bottom tank to accomadate a failure.

As anyone that has ever run a sump knows, gravity will sooner or later.

All that being said, I am going to have to build one.

PROF, WELCOME TO FISHLORE

You found one of the truly classic DIY posts....YES TIMG is still around, a little worse for ware maybe but he stays in touch. I can't say if this particular set up is still up and running, as he moved, and some of his tanks didn't make it.....I'll touch bases and ask.

I've done it with a gallon glass jar and set it on some bricks on one of the shelves in my pond just to see what would happen. unfortunately most of my fish are too big to swim in that small of a jar, but they did try to stick their noses up in the jar. I guess they like looking out at us as much as we like to look in at them.

I hope all of you that are thinking or have already done this type of setup have thought about power outages. Hopefully you have something backing up your tanks power source if the main power to your house goes out. If not then when or if you power ever does go out, your going to have a ton of water everywhere and maybe some fish on your floor.

I just thought about this while I was checking out how this setup was achieved. Thought I would share with everyone, just in case you havent already thought about it.

Good luck

gremlin

it would depend on how you did it. With the jar upside down, there is no relying on power. However, one that is plugged in relying on sucking air out of the top would have to have some type of battery or generator backup that would automatically kick on in case of an outage.

these tanks are set up like a dog dish only way the water goes down is if there is a space to escape too. power outage would only be a problem for your heaters and pump stop pumping. the water will still stay suctioned up in the hanging tank.

wow awesome tank.. someday I WILL do this

Kewl... you found Tims DIY threads...
NIce!

thats sweet dude nice real nice i think i will pass on doing it lol

wow dude u are crazy.... but very good.

I love this tank concept. I'm not sure why there are so many comments about how crazy this is! Did nobody pay attention in elementary Science class? News flash: the air pressure of the earth's atmosphere will keep the water in the upper tank without any pumps once the air has been removed. What you have to watch for is evaporation, too much of which would lower the water level in the bottom tank to a point where it breaks the seal dumping all the water out. You also must be careful when cleaning such a setup not to remove too much water at once or the top tank will dump out on you. The guy in singapore really has the idea, I'm putting one of these features in my friend's koi pond in his back yard. Wish me luck!

Good luck - please post pics when you are done!

Good luck on your project.

I am working on the logistics of where to place this set up so I can build 1,only problem is,I will have to remove a few aquariums,and temporarily relocate some fish. This is an awesome concept,and simple.

To clarify a few points made about power failure and the water all coming out,that wont happen. It is kind of like a dog dish,but it's more like the setup for a water cooler with the 5 gallon bottled water on top.(I am looking at my water cooler that's why I see the resemblence) To clean it,as you siphon water from the bottom,the seal is broken by the lowering water volume,then PRESTO big air bubble,gurgling as the water drops,then poof,seal is reachieved as the water level reseals itself,and water level is maintained. The only time you would have to worry,is if air is being pumped in (air bubbler/aerator) then the pressure from the air would slowly push the water out of the bottom,so removal of that air is required,but if the power went out,no air would go up,therefor no need to pump air out.

I AM DEFINITELY MAKING 1,just need to figure out where to put it.AWESOME

Hi everyone,
I'm a hobbyist from Malta. Unluckily I am currently without any fish tanks for a number of years now but big plans are simmering for the year to come.
Whatever. Enough about me.

I came across this open bottom aquarium set-up through Youtube and got brainstorming about it big time.

Some helpful vids are available on Youtube by searching "romaurie effect".
A particular guy seems to be using refrigerator compressors to set up the vacuum. I think a sealed aquarium pump as suggested earlier in this thread is way quieter.
One small problem is that in the long-term, water vapour will short circuit the pump as reported earlier on. How is this overcome?
How do you make this baffle?

Romaurie

The compressor does not need to run continuously.A small compressor, say 1/12th. H.P. is very quiet.Once the vacuum is "pulled" the water remains in the inverted section.I am now using a cheap refrigeration process timer to run the vac pump 2 minutes every hour to provide extra aireation.A small water pump circulates water from the open section to the enclosed section.Also, every time a fish enters the inverted section, it displaces its mass in water to the sump.when it leaves the oxygenated water returns.

I am reading this for the first time right now and I really like this concept. A few thoughts though, first of all, I am not sure I understand how you are going to add o2 to the water if you are just recirculating the same air through the tank over and over again. After a few days, the air will become depleted of o2 and the same o2 depleted air will be pushed through the water. Now, I imagine the air will reach a certain equalibrium as the bubbles gain o2 from the water. In the end though, your o2 is coming from the rest of the tank thats getting its air from your room, recirculating it in the top section seems to just add a little bit of visual appeal.

soldieroffortune1974

You're correct about the oxygen coming from the water's surface. Agitation/circulation is necessary,for more than just visual appeal. If the water remains "sealed" in the top portion without any movement or circulation it will become stagnant and toxic gases will build up in the water. The vacuum removes the air along with the toxic build up (if present).

1 of Romaurie's videos explained that he was using an air dryer on the return from the compressor as an attempt to remove moisture and toxins.He never did state how well it worked at removing the toxins,but his set up is visually appealing and efficient. the same effect can be achieved with a Venturi design and not need the compressor.
