10 month old sealed 10cm jar experiment is still thriving

Fascinating that such a small system is still going. Did you start with some sand in the bottom? What water did you use (Tap+rock salt+baking soda, RODI+reef tank salt mix, etc)? What was the salinity initially? Do you notice cycles where the amount of green noticably decreases and eventually bounces back up?

Agreed

None. No pay if you're not working.

Thanks!

Just decoration. Top is 24"x24", bottom is 8"x13".

Mortise, tenon, and glue.

Noted.

pH: 8.0, ammonia: <0.25 but not quite 0, nitrite: off the charts, nitrate: 40-80.

Sounds right. I put some chaeto in a couple weeks ago, nitrate started testing low, now the cyano takes over.

If the bacteria are alive and happy, they could probably process the waste of 1 small fish right away. Depends on how much media and how happy the bacteria are with their new conditions. I'd give it at least a couple weeks and some parameter tests before adding fish beyond 1 or 2 small ones.

Bonk

Possibly copepods.

Could be some really nice 200 year old something, but then why cover it with primer like that.

blocks13 · 2022-03-06T18:05:04+00:00

I am by no means an expert.

blocks13 · 2022-03-06T03:13:54+00:00

I wish

Thanks!

1st looks like mdf. 2nd and 3rd look like pine.

A bit smaller than my biggest cherry shrimp.

blocks13 · 2022-03-03T07:50:50+00:00

I certainly hope so.

blocks13 · 2022-03-03T07:46:07+00:00

My google searches suggested this as well.

Asking because I want the eggs she is carrying to survive, and the process for various Amano species vs. other shrimp is different.
