I hope you can do just that, jay. As odd as it sounds, it's actually easier to maintain a larger tank as opposed to a small tank. Changes are much more gradual in a large tank, giving you time to correct the problem. A small tank can turn over in a matter of hours with little to no wwarning. On another note, you can create a habitat for pods with an HOB refugium. It won't produce the volume that I'm seeing, but it will definitely help. Your dragonets will love you for it. Just something to consider until you upgrade.
Thanks, sweatervest. In the dark area on the right side of the screen (0:13), you can see a tiny bit of the live rock rubble. One side of this chamber is filled with rock, and my skimmer takes up the other part. This is where the majority of the amphipods live and breed. Some live in the macroalgae and small amount of rubble in the refugium chamber, and many live on the filter between the refugium and return chamber. I have pods basically living from one end to the other. I find them in the DT after lights out, so it's all good. I may have gone a little overboard, but several months ago I started seeding the tank and refugium with pods. Over a period of a couple of months, I introduced over 5000 amphipods and copepods. After I got my dragonets, I added a 16 oz. bottle each of Tisbe and Pavocalus . That's been a few months ago, and it looks like they're well established.
