Buyers’ Guide

What are some things I should consider when buying lights for my aquarium? 

There are a number of different aspects that go into deciding which aquarium light is best for you and it’s a good idea to think about them before you go out to actually buy one. Doing your research and knowing what you’re looking for in an aquarium light can make it very easy for you to make your decision. Some of the factors you should think about are: 

  • Build Quality 

Lighting is an essential piece of equipment that usually hangs above your aquarium. Since it’s usually placed at such a precarious position in relation to your fish tank, you’re going to want to make sure that it’s made from sturdy, high-quality material. You don’t want aquarium lights made from flimsy material that may break or fall apart after some time. 

While most aquarium lights hang high enough above aquariums to not come in contact with water, it can be an added bonus to get lights that are water-resistant or splash-proof. 

  • Customizability

Depending on the type of fish, aquarium plants and live rocks you have in your aquarium, you may want to have some special lighting conditions that would be most effective towards their growth. 

For that, it’s a good idea to look into lights that have different modes and customization options so you can adjust them according to your needs.

Some lights even come with a wireless controller so you can program them without even getting up from your chair. 

  • Aquarium Size

Obviously, the size of your aquarium will play a big role in deciding how big or small of an aquarium light you want to get. If you have an aquarium that’s very deep, you may want to invest in a higher intensity light so that it will be able to penetrate all the way to the bottom of your fish tank. 

You can even think about getting multiple aquarium lights for a single aquarium.

What are the different types of lights available for aquariums?

There are a number of different kinds of lights you can make use of to illuminate your aquarium. The main types of aquarium lights are: 

  • Fluorescent Bulbs/Tubes

This type of lighting usually comes with a fish tank and can be used as supplemental lighting. If you have a fish-only setup, this type of lighting might work just fine but we recommend that you switch over to something more controllable as fluorescent lights don’t have a lot of penetration power and they are very power-intensive as well.

  • Metal Halide Lights

These are by far the most intense kind of lights you can get. They have amazing penetration power and you can get these if you have a particularly deep aquarium and you want to get light effectively all the way to the bottom of it. 

We recommend investing in a chiller if you’re going to get these lights because they tend to heat up the temperature of the water. 

  • LED Lights

LED lights have quickly become the most commonly used lights for aquarium lighting in today’s day and age. This is because of a number of reasons: they shine very brightly, they use energy very efficiently, they are very long-lasting and they are easily programmable. 

LED lights also do a very good job of mimicking natural sunlight and moonlight which is great for your fish. You want to make your fish’s environment as close to their natural environment as possible as this will make them a lot more relaxed and less prone to disease. 

Do I really need lights for my aquarium?

Yes. You need lights for a number of reasons but we’re going to list down the important ones for you:

  • Fish need light in order to grow and thrive. European fish require about 8 hours of light every day whereas African fish require 12 hours of light. 
  • If you have live plants in your aquarium, they require light to perform photosynthesis and grow. 
  • Fish have beautiful, brilliant colors and you’re going to need effective lights if you’re going to observe them in all their glory. There’s no point having an aquarium with beautiful fish if you can’t view them properly.

What’s an efficient way to set up lights for my aquarium?

Most aquarium lights come with an instruction manual so it’s a good idea to follow them exactly. 

Some general things to keep in mind while setting up lights is to look at the lighting equipment and judge what tools you’re going to need and have those tools with you when you’re going to set the lights up. You don’t want to leave your aquarium lights half-attached to your aquarium while you go look for a small screwdriver or something of the sort. 

Some aquarium lights come with extendable brackets so you can easily mount them onto your aquarium regardless of its size. It’s a good idea to ensure whether the aquarium lights are waterproof or not. If they aren’t waterproof, make sure that they are completely dry from all areas before plugging them in and turning them on.

Does the color of the light affect life inside my aquarium?

Yes. Most fish and plants do quite well underneath white and blue-colored lights. 

This combination of light usually encourages photosynthesis in plants while also being pleasing to the human eye.

Frequently Asked Questions

When should I turn off my aquarium lights? 

On average, you can turn your lights off anytime you want as long as your fish are getting about 12 hours of light every day. Most aquarists tend to turn off their aquarium lights when going to sleep since they would much rather have them on during the day. 

Never leave your lights on indefinitely as this can lead to a number of problems such as algae breakouts and stress-related diseases in your fish. 

If you feel you might forget or that you may not have time to turn your aquarium lights off and on each day, it can be worthwhile to invest in a light timer. This will automate it for you so you don’t even have to think about it. 

Can’t I just use sunlight as a substitute for aquarium lights?

You can if you want but we definitely do not recommend this and the reason for this is quite obvious: you can’t control the amount of sunlight your aquarium gets each day. Sunlight is very inconsistent; It might be cloudy one day, it might be rainy the next and it might be overwhelmingly sunny the day after that. This can cause a number of problems for the aquatic life inside your fish tank. 

Your plants may start to wilt and die, your fish may become stressed and you may start noticing algae growth inside your aquarium as well. That’s why we recommend that you definitely keep your aquarium away from direct sunlight and use a controllable, artificial source of light to illuminate it. 

Do fish go to sleep when aquarium lights are turned off? 

Yes. Fish definitely do have sleep cycles and having a light that you systematically turn on and off at regular intervals can help them develop these sleep cycles. This is healthy for them and will help them grow and thrive.

Can aquarium lights contribute to algae growth inside fish tanks? 

Yes, they can. If you shine too much light or a high intensity of light for too long on your aquarium, this can definitely lead to algae breakouts inside your aquarium. 

If this does happen due to your aquarium lights, a good way to tackle this is by leaving your aquarium in darkness for a day or two.

How much light is generally needed by an aquarium for effective growth of the fish and plants inside it? 

The operating capacity of light when it comes to their usage for aquariums is usually measured in watts per gallon. We’ve already discussed how a regular aquarium that houses tropical fish requires about 12 hours of light. If you have an aquarium with coldwater, European fish, that would require about 8 hours of light. The operating capacity for these lights is usually somewhere between 2-5 watts per gallon. If you have a coral reef aquarium, you may need lights that shine brightly than for regular aquariums. Coral reef aquariums usually require lights that operate somewhere between 4 and 8 watts per gallon.

Final Verdict

There’s really no point in having a beautiful aquarium if you don’t have a decent aquarium lighting setup which can illuminate it effectively.

After months of testing, we’ve concluded that the MingDak LED Aquarium Light is the best one currently available. It will illuminate your fish tank wonderfully in order to bring out and enhance your fish’s colors, it provides great ambience in your room, it’s great for plant growth and it does all of this at a very modest price.
