Refugium
This is my new refugium. Its a separate tank underneath my main tank. The water is pumped through it and the types of things in it help to purify the water. I run its light at night, which helps to keep the oxygen level consistant while the light is off in the main tank. In the refugium, I have seaweed (caulerpa), rocks with little creatures growing on them, and a layer of sand.
