With all the lights around the tube how would they clean the algae that will eventually build up .

I don't understand how the water stays above the tanks. Why doesn't it flow right into the tanks and flood them. I just can't wrap my mind around it.

If air can't enter the tube to relieve the pressure, then it won't flow out. As long as both ends of the tubes stay submerged it wont empty.

You can see the same forces by taking a glass submerged in water and lifting it bottom up with water inside the cup, above the waterline. as soon as the rim touches the surface air rushes to the top breaking the seal and the water falls out. you could potentially have air inside the top of the tube if you put a bubbler at the mouth of the tube. the air would displace some of the water in the tube.

i dont think the fish would like the low pressure

Did they tell you so?

There wouldn't be a significant difference in pressure.

Cause fish never go deeper than the 24" of the average fish tank...

That would be sweet if you had a massive tank in one part of the house and had a 3' diameter tube going right way through the house, watching pimas alligator gars and aros swimming over head would be awesome, but i think i'd rather spend that money on a massive in-built tank

It was alsoposted a year or two ago too.

I'd like it better if it was going from one 300g tank to another 300g tank.

i agree... that be cool to see some monster morays swim through those too
