Why do I need LED Lighting for my fish tank?

Not only do LED lights add to the aesthetic of your aquarium, they also aid in the temperature and lighting control that are necessary for the survival of your fish and plant life. Plants must have a light source, as it allows them to maintain photosynthesis, and most fish species thrive in a light that mimics that of natural sunlight.  In short, LED lighting allows your salt and/or freshwater aquarium to look and function at its best. The primary benefit of LED lighting, as compared to other types of lighting on the market, is its cost effectiveness. While it may cost slightly more upfront, LED lighting is significantly more energy efficient, using up to 80% less energy than other aquarium lighting. Saving you money on your monthly energy bill, LED lights generally make up the cost difference in their first year. It is also important to note that LED lights are designed to dissipate heat so that you never have to worry about your LED system overheating and creating a dangerous temperature for your aquarium life.

Factors To Consider

Ease of Installation

Be sure to read the manual to determine if you need to gather any extra tools or equipment or purchase any extra products to install your lighting system. For easiest installation you will want to look for products that come with adjustable brackets or legs that simply allow you to clamp the system in place.

Intensity and Spectrum

Many LED systems come with effects that allow you various degrees of control over the intensity and color of your lighting. Some systems even allow you to set up a 24-hour cycle for your aquarium that mimics the natural cycle of the sun and moon. If this is important to you, then you will want to be sure to consider this technology when making your purchase.

Type and Inhabitants of aquarium

Most LED systems are designed to be optimal for either freshwater or saltwater wildlife. As you purchase your plants and fish, be sure to take note of the type of lighting that is optimal for each species so that you can consider which LED lighting system is best for your tank. Saltwater coral will need different lighting than freshwater java moss. A clownfish will need different lighting than a betta fish. When choosing a light, you should be mindful of the inhabitants and their needs.

Size and Depth of Aquarium

Each LED light system is designed to have a specific lighting coverage. If you have a larger aquarium, you’ll need to purchase a light with a greater coverage size or depending on the light, you may need to purchase multiple lights. Also depending on the depth & inhabitants of the aquarium, specifically for planted and reef tanks, you may need a higher or lower intensity light.
