Note: The Oceanic BioCube has been re-branded as the Coralife BioCube. Coralife and Oceanic are both brands of Central Aquatics.
This page features many BioCube Accessories that can be used to upgrade your BioCube. You can purchase BioCube LED Bars for the empty slots in your BioCube—the 14 Gallon has one additional slot for a BioCube LED Bar and the 29 Gallon has four additional slots for BioCube LED Bars (NOTE: The Oceanic BioCubes do not have this feature). The Coralife 14 & 29 BioCube Protein Skimmer is a good idea for any saltwater tank and a must for a reef tank. The BioCube Circulation pumps is also a good idea for any reef tank—reef tanks need more flow than fish only tanks.
