My 250ml Reef Tank

[MossyFroggyLove]

Heyoo guys, you read it right! It is literally a 250ml reef tank. I am using a glass jar. I was wondering how small could a reef tank possibly be. So, a glass jar, no pumps, no filter, just sunlight/house light. Is it possible. Well since i already have an established 20g tank. I just grabbed some sand, some water and 2 pieces of rubble for the jar. AND, the jar doesnt have a chiller, meaning that the temp would be around 28°-30° celcius, whereas my 20g is 25° celcius. And the firs inhabitant i have adde are some spaghetti worms and a small clump of chaeto, a small bristle worms and a small vermetid snail.

Since there is no water movement, there wont be much gas exchange so i haveto leave the lid open. What do you guys think of it?

Would this be considered a micro reef?

Guys! I just added 2 bristle worms in. Each about an inch long. All seems good so far

I JUST ADDED CORALS!!! A baby mushroom, a small kenya tree branch, a small xenia clump, and a captain jack palythoa(2 polyps). I fragged them from my 20g reef tank. Hopefull they do good. The palythoa is already opening up!

We already have nano and pico reefs. This would be a femto reef, lol.

Update:
All the corals except for the palys have died. But hey, nothing wrong with a palythoa only tank

Did you do any w/c or replenish any evaporation?

I love this btw. I might copy you.

"I just added 2 bristle worms."

Priceless!

I do a 90% water change whenever it smells unpleasant. I add 1ml fresh water to overcome evaporation. Every few hours i will suck up some water with a syringe and pour it back from the height of 4-6 inches to increase gas exchange. Seems like palythoas are the most indestructible corals. Even my kenya tree died.

Good actions. Keep it rolling!

What if you added an air stone and ran a small amount of air with a small pump, you would get circulation and water movement from that and you could add a valve to control the amount of air.

^ seems like a GREAT idea

Great idea! But the diameter of the jar is only 5 cm. Putting an air stone would take up 20%-30% of the available space, though i think it will still work. But, i also want to see if u can do a reef tank without electricity.

Also, once i have finished my jam, i will start a 100-150ml reef tank

What about ditch the whole stone some way… if you can jam/glue a piece of stone inside an airline that’ll still allow air through. Idk if the single bubbles from just an airline would be super worth it but maybe.

Great idea! I might try that once i get the other reef tank so it would be worth to set up a air pump

You could just stick the airline under a rock and set it to like a bubble or two every second.

Nice idea. I already have an old air pump lying around. I might set it up later, after i have my lunch

I'm heading to bed. Goodnight. I will check in tomorrow. I may have to try a pico reef. I'm going to hunt for a cool old jar or something to use.
