This tank has been upgraded to LED dual channel (white, royal blue) lighting from RapidLED This is now a professional quality tank. The lighting upgrade is not only expensive, but the install is time consuming. This is no longer a standard BioCube; you're getting a high-end tank and lighting system. Note, you'll need a controller to run the lights. The most basic of which is manual and is included. You will need a little bit of electrical knowledge to wire this but detailed instructions from RapidLED are provided. For automated dimming there are two options: Storm controller + 10V converter: http://www.rapidled.com/coralux-storm-led-controller-with-10v-analog-converter/ Bluefish: http://www.rapidled.com/bluefish-controller-wireless-sunrise-sunset/ Also this tank can be run on a single Apex computer system which is what the original owner used. Do not hesitate to contact me with any questions that you might have. Asking $150 or best offer.
