It looks like “the world’s oldest terrarium” possibly has a cork lid. Which technically wouldn’t make it sealed. Like your jars that are completely sealed with glass lids. The air exchange that a cork lid provides would drastically change the results.
I really need to make this. Also, can you keep a small animal such as a small fish in it and make a little airtight closable tube to add food for the fish and allow the fish to live while doing this?
There’s no evaporation, it’s sealed. The evaporation that occurs within the jar stays within and automatically compensates. 🙂 There’s no human interference to the experiment.

I love the idea of having your own self-sustaining ecosystem at home 😊
It really is!
Great content! The part about the oldest terrarium was pretty cool!
Hey danny, a question please
U changed from oase to ehein
Surface skimmer
Which do u find better? & Why did u change
For a 20 gallon tank like yours?
How’s does oxygen get into the jar?
The "algae" may be cyanobacteria, which may have developed due to poor air circulation. This may be caused by keeping the jar sealed.

So this can never be opened or air introduced. Correct?
It can be, but the concept is to keep it closed forever and let mother nature form her own balanced ecosystem within the jar.
I hope my reef tank will look this amazing one day!
it's not even a reef tank and it looks like a jar of garbage
This is such a cool things to do!
It really is!
half a year - 6 months :)

DO NOT PUT FISH IN IT. FISH NEED PLACE TO SWIM, AND THE WILDLIFE IN IT MAY KILL IT
I have one thats going to be 5 years old
Do you top off and compensate for evaporation?

Amazing ❤
Thanks 😄
Didnt you made one with seawater ?
Yes! That’s the one I showed later in the video.
Hi😊
Hi! 👋
Cool video but its Photo-syn-thee-sis just fyi.
