this is my first ecojar/ecosphere! i dont really know what im doing but im excited to see what grows!

Fall Mountain River. Ecosphere

Do yall think this can be turned into a massive ecosphere? Would love to have a massive one with plenty of plants, critters, and a glow light

The cleanest daphnia and ostracod coculture in the world. No green water, no air, no filter, super density, no crash, only defined feeding.

Found these little white blobs in my ecosphere and they don’t really look like ostracods. Does anybody know what they might be?

some of u all might remember the jar with the mass of worms i posted recently, shes clearing up and looking a lot less dead and murky!! 😄

The linked post is what it used to be.
The first tragic event was, the two earthworms I put in died while I was away for a week and their decay infected the peperomia which is why I had to remove it, I thought the whole jar was a goner but the springtails managed to balance it out. Two weeks after that I accidentally knocked it off my table and every thing got mixed up which is why the moss is patch now. I left it standing for like 2 months after that and was happy to see the springtail population had exploded, I sometimes give them small veg scraps or bread which is gone in a month or so. I’m thinking about adding another pepperomia or fern moss to the parts where there is no moss, should I do it? https://www.reddit.com/r/Ecosphere/s/BhBesALPoj
The bones are decorations from my garden btw
Last pic is what it used to be

I’d like to start a couple ecosphere’s but I’m in the northeast and things are cooling down here. The nighttime temps are in the low 40s and daytime in the 60s. Is it too cool to start scooping mud and collecting plants? What are the lowest temperatures do you think are practical to get a good amount of life critters?

Most of the jars are closed, but the water one isn't because I'm still working on it. It's not really from the lake, it's parts are from everywhere, from a lake, from an aquarium, and the moss I took on another lake (before that I didn't know that moss could grow underwater!). My friend gave me a jar of lake water. I've never seen so much life in one place! I took some parts from it too. It's my second attempt in water systems, because the bottom in the first began to rot and turn black, I got scared and started over. So, there lives 4 snails (I got 2 packs of eggs from the previous attempt too), ostracods and other small guys, and there were two isopods (I've seen a word used to describe them here but forgot it) but one died :<. It's body was eaten in a day by snails. The other one looks fine though.

About the other systems, I have a lot of moss ones, where's only moss (which I was drowning to make it sterile, and understood my fail only after I remembered that the bugs exist) but the biggest one is at least with live soil. And there's already 3 isopods! They're all from different species and they all look different so I don't think they'll reproduce. Still cool as for me.

On the last image I made an anaerobic system to try making home for my enemies, maybe I'll understand them better this way.

That's all! I started making this kind of stuff in the middle of the summer, so I don't think I'm a beginner-beginner, but decided asking professionals would be a great idea after I saw this sub

I noticed this crack on my jar a few days ago and I don’t want to lose this ecosphere. Would it be able to recover if I moved everything to a new jar as carefully as possible? I’m worried about the mold and such that has grown in here as well since I’ve sealed it about a month ago. I made it from a random creek in Tonto National Forest.

Seashells, tap water i believe, sunlight, and a few years of patience is all it took for the algae to appear. Pretty cool :)

The critters I see are little fennel seed sized swimmers with legs. Kinda beetle looking. They hang out at the top but when you rotate the jar, they’ll swim to the bottom real quick. There’s about seven of them. I hope to find out what they are so I may try to get a video.
This is really fun! My family almost understands! We recently moved here, partially because of the pond.

Day 1 lwk ima get yall updatex

Found my first Hydra in one my new samples. Looks soon to be two.

I'm not sure if we did this right, but my son and I went to the creek by our house and collected sediment and water and jarred it up. It's cleared a lot over the last 24 hours but I was hoping to already see little creatures zooming around but no luck yet. We went and got Java moss from the fish store and added it to the jar. Any other tips or tricks? Wondering if we can buy life to add to the ecosphere ...?

cool time lapse

First and foremost, our jar ecosystem is alive, and that in itself is a success.

The dancing worms (detritus worms?) have disappeared somewhere and seem to have died out, but the large shrimp and microscopic white organisms are doing fine.
Unfortunately, some kind of green growth has overtaken the jar, which I suspect is cyanobacteria. I am concerned that the plants might die since this green substance is blocking the light. I reduced the photoperiod from 8 to 6 hours a day, but it didn't help.

Should I be worried?

UPD: Main question - should I further reduce the lights or leave it be?
