Aquarium Lighting

Aquarium lighting improves the look of your aquarium and the quality of life

Too often lighting is overlooked when setting up an aquarium. Unfortunately, this does more than affect its appearance. Without proper aquarium lighting, your aquatic life may suffer. The key to ensuring this doesn't happen is to simply select the correct type of aquarium lights that will help you replicate a natural environment.

Types of aquarium lighting

Due to numerous advancements in lighting technology, there are several different types of aquarium lights available, which make recreating natural conditions easier than ever. Here are few of the most commonly used types of aquarium lights:

Halides: Creating a very intense light, this type of aquarium lighting is often used to highlight certain areas of the tank.

Metal halides: Perhaps the most powerful form of aquarium lighting available, these are commonly used for soft corals and clams.

Fluorescents: This type comes in a variety of colors, which allows you to decide which ones are best for your tank. Most often, full spectrum aquarium lights are used to create a daylight feel while actinics are typically used for coral growth.

Compact fluorescents: The major difference between compact fluorescents and fluorescents is that the compact ones typically last longer and are more efficient. In addition, compact fluorescents are smaller and require less space. 

Choosing the right ones

As you consider the different options, it's important to think about what type of aquatic life you have and any specific needs they may have. If you aren't certain which type of aquarium lighting is right for your tank, here's a helpful guide:

Simple fish tanks: If your tank contains just fish and no other aquatic life, standard or compact fluorescent aquarium lights will suffice. You can choose the spectrum of bulb because it isn't as important with these types of tanks. However, it's best to avoid the standard bulbs, which may encourage brown algae to grow. Instead, select bulbs that are designed for aquarium lighting.

Freshwater fish and plants: For tanks that have freshwater fish and plants, you can also use the standard or compact fluorescent aquarium lights. Typically, the rule of thumb for these environments is two to five watts per gallon, depending on the specific needs of your plants.

Saltwater tanks: With fish, invertebrates, and corals in an aquarium, a powerful aquarium lighting system is needed. Metal halide aquarium lights are recommended because they are most comparable to the sun. This intense type of light is what most corals require.
