Aquarium Filters

Although the primary method of filtration for a nano reef is normally just live rock and sand, having a second method of filtration isn't a bad idea. Bio Wheel filters are a pretty popular filter for aquariums, and will help water movement if nothing else.

And if bio wheels aren't your cup of tea, there's nothing wrong with a good ol' Whisper powerfilter. Whisper filters are cheap and reliable.
