It's like a spaceship for sharks.
"Life support system" were the three key words that convinced me to do a video about an aquarium. Because yes: behind the scenes at The Deep, an aquarium in Hull, there's a life support system, and it deserves that name.
Thanks to all the team at The Deep! More about them: or on their channel:

    I guess technically it's more of a "space station for sharks", or "space station for all sorts of marine life", but that doesn't sound quite as catchy.

    Is this the video you were talking about that has an A.I.-generated title?

  • Haggisking

    I have one of these at home (albeit "slightly" smaller :D) keeping the fish alive is relatively easy, all you need to do is keep the bacteria alive - that's the hard part! (and don't even get me started on corals...)

    It's struck me before how managing an aquarium is like managing a spaceship (or maybe a reverse submarine) for fish many times while doing stuff like carefully reading and adjusting the the dissolved co2, nitrogen, oxygenation and water flow of some of my home aquariums and setting up filters and plants to scrub and recirculate the water. Aquariums really do have a full on life support system. With just as many design methods to create one as there are for spaceships.

  • sKai0216

    Is it just me or does Ben kinda looks like Veritasium?

  • Festivejelly

    Not really anything to do with space but okay, I understand the need for a semi clickbait title. Id say its more a Life Support System for sharks.

    Wow I’ve been there! Took ages to wait outside and it was raining, but it was a wonderful experience

  • sharpfang

    And this device here controls how wet the water is. Sharks need very wet water to survive, and as the water sits in a tank inert, it get less and less wet. This machine restores it to the original, natural wetness through means of splishing and splashing. For every splish there must be a splash, so this part here counts them and applies a splish or a splash from the respective reservoirs to restore the balance.

    I really wish I knew what on earth they mean by school for gifted axolotls. I mean what are those axolotls up to? what do you have to do as an axolotl to prove that you are gifted? Where are the non-gifted axolotls. This may be my Attention Deficit but I have not been able to take in any other information from this video since seeing that sign.

    I thought this was clickbait but then I realised how interesting and cool this really is. It's like that giant greenhouse experiment in the desert somewhere, but for fish.

    Hey Tom, can you make a video on the navigation satellite system "Galileo". A system developed by ESA to compete with the GPS from US? As far as I know it is supposed to be way more precise and also more accessible for private people / businesses. Sounds like a cool thing and brings the European countries closer together since it has people working from all across the EU and companies from all the countries contributing to its development. I really like it's idea and I am even considering just doing my master to work for ESA and hopefully be able to contribute to this project in the future or a new one. I just really really like the idea of people from different nationalities coming together to create something to make everyone's lives better, even when those countries were at war not even 100 years ago. Thanks :)

    Damn, top notch video!! I always enjoy your videos, short and full of information. Just to the point! Though I would have loved an explanation on why the microbes where exposed to UV-light. My 'slightly educated' guess is, that this is how they dispose of them. EDIT: By 'slightly educated' I mean the fact that UV-light is non-preferrable to most organisms on our planet (the atmosphere of the earth absorbs most of the shorter wavelengths - one of the keywords here is 'ozone'), which is why we humans have a chance of getting skin cancer by being exposed to the sun for too long. In short: UV-light alters our DNA, which can lead to cancer when our immune system can't dispose of those altered cells.
