Whoa! Check out this freshwater tank.

That's pretty sick!!

I have trouble figuring out the right PVC dimensions to avoid cavitation and look what that guy can do! LOL

How in the world does that work???

But the fish have to swim straight up a narrow column - if I was a fish I wouldn't do it.

i love this gets posted roughly every 6 months or so.

Very cool!

 

 

It looks like he has the "pipes" under the water level of each tank by about 6 inches. What he would have had to do was set this up, then have some sort of vacuum on top in order to suck all of the air out and as the air was sucked out, it would pull the water up. Would have to have been a strong vacuum though. As long as no holes form in the pipe, and the end of each pipe does not come out of the water, it'll work.

Yep, that is what he says he does, there was a discussion page he posted about it one time.

Both ends of the big overhead tube are submerged in tanks of water. It's just like a big siphon tube with the water level equal at both ends. Since there's equal pressure on each end, the water in the tube goes nowhere. Now, if you were to take some water out of one tank, the water in the tube would flow from the other tank to the one that is lower to re-balance the water level between the two.

 

To keep the water in the tube fresh and oxygenated, I hope that he's pumping water from one tank to the other (either through a sump or directly) in order to set up a current between the two tanks.

An even bigger question (and job) how does he keep it clean?

Good question. Mag-float?

I think he said he had a pump at the very top continuously pumping from there into the tanks to eliminate air bubble build-up (like the CPR overflow boxes) and set up a current all the way through the pipe

That makes good sense. Thank you.
