Who Should Buy an Aquarium Light

If you have an aquarium, you should consider purchasing an aquarium light. If you have plants, it’s a must, because the light will help the plants photosynthesize, grow, and remain vibrant. Fish often do better when the lighting in their tank mimics what their natural environment would be. Since keeping the fish tank in a window might cause the water to get too warm, particularly during the summer months, an aquarium light does a better job of providing light without providing too much heat. In addition, you might enjoy seeing your fish and plants with the aid of a light that has special effects. Some people even use blue lights as a nightlight.

Important Features to Consider

Aquarium lights should have a few important features. Here’s what to think about before you make your purchase:

  • Modes. Some lights will have only one mode, while others will have many. Think about whether you will want to use different effects. If you do, find a light that includes those effects.
  • Type of aquarium. Depending on the type of fish you have and whether you have plants, you might require a light with bright lights or a light strip of a certain size. Consider the size of your aquarium, whether you need a planted light, and whether your fish have any specific lighting needs.
  • Water-resistant vs. waterproof. If you will be submersing your light, you will, of course, need a waterproof product. Many aquarium lights are simply water-resistant, however, which means that while they can withstand a splash or two of water, they shouldn’t be submersed. Read the product information carefully to determine whether yours can be put underwater if that is what you want to do.

Frequently Asked Questions

What are aquarium lights?

Aquarium lights are lights that illuminate an aquarium. Depending on the type, they might clip to the side or top of the tank or you might put them in the water. Other clip under the tank hood. Some lights are good for tanks with plants while other are not bright enough for planted aquariums.

Do I need lights in my fish tank?

It depends. If you have fish without any special lighting needs, you don’t specifically need a light. If you have plants, you do need a light. Also, some fish have specific needs when it comes to lighting. When you purchase your fish, talk to the person you are buying them from to find out if your fish needs a light to thrive.

What type of lights do I need for my aquarium?

Most fish and plants do fine with fluorescent and incandescent lights. Deep aquariums can do better with power compact lighting, because this type of light penetrates the water to larger depths than traditional fluorescent and incandescent lights. Metal halide lights are another option, but they heat up the water. Talk to your local aquarium or fish expert for more in-depth advice about which type of light you should use.

How much light does my aquarium need?

It is best to have your aquarium light on for approximately 12 hours per day. This gives fish and plants the benefits of the lighting while also allowing them periods of darkness, which both plants and fish need. Leaving an aquarium lit 24 hours per day can cause your tank to be more hospitable to algae, which is something you want to avoid.
