    OMg now you got me goin.. :rolleyes: But it all is very simple if you ask me and i'm about 99% sure it has to work.. If you look at such an air difuser darrel points to, it is one such as this.

    DSCF7378.jpg

    This works with the force of nature, the venturi creates a pressure drop or an up speed in flow whatever (not that important to me right now) at the left hand side, this makes air sucked into from the atmosphere instead of water being sprayed out. Now this venturi is about going from 16mm to 10mm back to 19 mm where the air is sucked in. There is a cross shaped septum placed at the 16 mm section in front of the venturi, this will also reduce and scater the water flow, probably also to create some vortex and make the water go wild behind it. The air which is sucked in behind the venturi gets scatered into little tiny bubbles and difused even more along the way. That's all it takes to difuse air with a venturi, as long as water flows it works and doesn't spill a drop of water. :)

    An educated guess, if you push through presurized co2 instead of air, it doesn't need to be that much say for example 0.5 bar / 7 psi or even less it will get scatered and difused as well.

    My theory says because i think it's only logical, that if there is a venturi close enough in front of an inline difuser, then already (Ceramicaly) difused co2 gets difused even more. :thumbup:

    Just going back to zozo s point about shame its temporary and understanding Paulos point about it costly and however many aquascapers,hobbyists returning it still wouldnt generate enough to make it viable,perhaps it could be promoted from a educational angle,much the same way as school trips,universities and the like getting involved,maybe having special guests,naturalists etc ma ybe phone call to Sir David Attenborough, Brian Cox would promote to the general public.

    Hi, Paulo made a good point. From the start it was thought to be temporary. The art of the visionary Amano is perfectly integrated in the , educational misson, of oceanário. The role of these aquarium is very important in Portugal (along with others) and we are ver lucky to be near and enjoy the evolution of these master piece!
    So we'll keep sharing and enjoying these master piece,
    cheers

    Hey guys, from Portugal and not only. Do you have any info whether this exposition will be working some more time? I'd like to visit Lisboa and especially this awesome exposition in next few months, but due to uncertain timeframe for my vacation and possible EU visa implications I'd like to know how much time I have for preparation of the travel. Thanks in advance.

    It's a temporary exhibition, but from the page https://www.oceanario.pt/en/exhibitions/temporary-exhibition/ there is one sentence in "Relevant Facts and Figures" that says "1.5 million visitors expected in 30 months"... that makes me think that it is supposed to be there for 30 months (2.5 years), so if it started on early 2015, I would say it should be there until mid 2017... but I'm just making assumptions here...

    Try to contact them https://www.oceanario.pt/en/contacts-us for a better answer.

    Old thread but given I've just signed up and I'm exploring the site I thought I'd chip in

    Went here about 15 months ago and OMG! The Lisbon aquarium itself is amazing but this tank it incredible. We spent a good hour just watching it. I've just had a look on their website and it's still there by the looks of things, so for those that haven't been I'd 100% recommend it

    Word of warning though - you will come back and want to upgrade in some form or another!!

    I had the chance to go and see it and until you see it, you won't be able to appreciate the beauty, it really is out of this world
    Can't believe it's a temporary exhibition, it should be kept as it is MR Takashi Amanos final work.
    Anyway I made a little video unfortunately because of the lighting on the tank it's not the best quality , hope you enjoy it anyway
