Reef Tank Lighting
Introduction
Reef tank lighting is a crucial aspect of reef keeping, and it's often surrounded by extensive discussion and differing opinions. Ensuring the correct lighting is vital for the health and growth of corals, as it supports photosynthesis?"the process by which corals generate the energy they need.
Key Considerations
The main goal of any lighting setup is to provide the necessary photoperiod, intensity, and spectrum for reef inhabitants to thrive. A common guideline, "watts per gallon," suggests using four to six watts per gallon for low-light corals and about ten watts per gallon for those needing high light intensity. However, this is merely a rough estimate. The height and overall dimensions of the tank are also critical factors to consider.
Innovative Lighting Strategies
One effective lighting strategy involves using a multi-light system with timers or controllers to simulate natural sunlight. Typically, one bulb is left on for an hour, followed by all lights for ten hours, and then just one light for the last hour. This method closely mimics the natural movement of the sun.
Lighting Equipment Options
Advancements in lighting technology have resulted in more efficient and effective equipment, with options ranging from affordable to expensive, depending on your tank's needs.
Fluorescent Lights
Fluorescents are a cost-effective choice suitable for many lighting needs. They remain relatively cool and can last for many months. Variants include Normal Output (NO), High Output (HO), Very High Output (VHO), Power Compacts (PC), and T5s. Power Compacts, with their twin tube design, offer greater light intensity and can last between one to two years. Fluorescents are ideal for shallower tanks, though they might not provide enough intensity for certain corals, like SPS corals.
Metal Halides
Metal Halides (MH) are the most intense lighting option, perfect for tanks deeper than 20 inches. They can penetrate deeper water and create beautiful sparkling effects that enhance the tank's appearance.
Conclusion
To establish a successful reef tank, it's essential to understand your tank's specifics and the needs of your corals. Make a well-informed decision about lighting, considering all relevant factors. Once you've done that, let there be light!
