Shutting down some 2.5gal tanks and did this last night...
Ignore the dirty glass:
Had some leftover Akadama from filling a new 20L. Have a few Red Sea Nano HOBs that are currently running on other tanks (have them doubled up so I can remove one without a problem) that I can use.
Maybe I should get it going and keep snails and a few mutt RCS culls in it. That way it's ready for any undesirable crystals mine throw at me? It's so small that I don't want more than 5-10 shrimp in it tops.
What the heck should I use this for? Should I use it? Guess we'll find out.
Now to go on the hunt for some nice driftwood or manzanita for the new 20L.
