About 3 gallons. $11 AQQA powerhead from Amazon with a preset heater that cost about the same. I modified the lid to hold a freshwater light (Fluval Wing Nano Fresh) I had leftover from another project.

Stocking is always changing, as this is my experimental tank. My current procedure is to throw in random handfuls of macroalgae from various parts of Florida every 3 months or so and see what happens. If after 77 days there is life in there that I want in my DT I'll move it over and throw in a new handful from somewhere else.

Running this fishless on purpose, so my current stocking is:

1 cerith snail
1 blue leg hermit
1 Calcinus tibicen (orange claw hermit)
Several Stomatellas
Amphipods (probably  Gammarus or something similar)
Munnid isopods
A very small tan hermit or two
Several of these really cool red macroalgae associated shrimp (probably in the genus  Hippolyte, most likely H. obliquimanus).

5 month update

Due to overgrowth and some algae issues, I didn’t feel like the tank was as stable as it had been in the past. And the whole purpose of this tank is a small enjoyable tank with minimal work and I had to reset myself back on that path.

I removed the items I wanted to keep in it, moved excess to my main tank

Drained 100% and converted to bare bottom. I felt the sandbed was trapping nutrients and making stability and maintenance harder, so I eliminated it. I’ve never done it before, and figured let’s see what this bare bottom hype is about!

Ive been bare bottom for 2-3...
