Water Change

The process of removing a certain percentage of water from a reef aquarium and replacing it with newly mixed saltwater. This process helps remove disolved organics, nitrates, detritus, and replenishes trace elements. In a nano reef, 10 percent changes are recommened every week, or 20 percent every other week.

Wet/Dry Filter

A biological filtration system that is exposed to the air to aid nitrification. This system typically consists of a large box that is placed underneath the aquarium. Water passes down into the filter over a filtration medium where bacteria remove toxins. The water is then pumped back up into the tank. A sponge or other mechanical filtration medium may also be used in a wet/dry filter.
