Aquarium Lighting for Your Freshwater Aquarium Pros and Cons (2022)

The proper lighting is essential for a healthy freshwater tank. LED lighting has a lot of benefits for your tank, and you should use it. You have many options for this type of lighting to choose something other than incandescent, fluorescent, or metal halide lighting. To ensure that your lights are bright enough and have the correct spectral range, you must think carefully about which ones to buy.

Aquarium Lights for reef tanks come in four different types:

It’s LED vs. Other Light Options:

Standard fluorescent bulbs, compact fluorescent bulbs, metal halide lights, and LED lights are the best for freshwater tanks. You can also choose lights that don’t use electricity. You don’t want to use incandescent bulbs because they’re only suitable for small aquariums and can get too hot, so you should avoid them.


Standard fluorescent lights are good at putting out a lot of light and not putting out a lot of heat. Compact fluorescent bulbs give off more light at a smaller size. They are often built into the hood of an aquarium, and they can also be bought as a separate bulb. In the wild, much freshwater fish had low lighting that Metal Halide lights could recreate. They also help plants grow in aquariums because they have a full spectrum.


However, this isn’t true for LED lights. LED lights run much more relaxed than standard fluorescents and metal halides. They can change the colors and intensity of the lights, and they work well in both fish-only and plant tanks as long as you choose the right one.

There are a lot of benefits to using LED lights in your fish tank, so you might want to set up a new tank with them or change the lights on your old one. These are:


They use less energy to run than other things, which is good because they use less energy. LED aquarium lights use less electricity than different types of aquarium lights do. In the first year to 18 months, your energy savings alone will cover the difference in the cost of an LED system from the old one.

Because LED lights don’t heat your aquarium water as fluorescent light bulbs do, your water will not get too hot when you put them in it. However, they still need a lot of airflows, so the heat they make doesn’t shorten the life of the LED chip and keeps them away from other types of lights.

Many people like the fact that LED lights last a long time. As a comparison, LED lights to last up to 50,000 hours (almost six years) compared to two to four months for incandescent bulbs, six to 18 months for standard fluorescent bulbs and metal halides, and up to 28 months for compact fluorescent bulbs. They will cost more upfront, but you will save the $500-$1,000 you would have spent on metal halide, T5, or compact fluorescent bulbs over five years.

LED lights can be dimmed and programmed, allowing for a natural dimming at sunset and the opposite at sunrise. It makes it easier for people to see at night and in the morning. It is perfect for fish that like to sleep at night because a dim blue light can be left on the tank to make it look like the moon and easier to feed and see. Even LED lighting strips to look like the moon’s phases every month. You can have a lot of fun with the remote or app when you change the lights. Then, you could let your intelligent lighting system figure out what colors and wavelengths will work best for your plants based on the temperature and the stage they’re at in growth.

LED lights come in a wide range of colors, making the tank look different. Often, they are sold by spectrum (Kor Kelvin). You can choose which best fits your needs. For example, the 8,000K white spectrum helps your plants grow and makes orange, red, or yellow fish look better. Add a magenta or magenta/blue LED, and you also bring out greens, blues, and reds, while giving your plants more help. The 12K white and magenta combination can be great for aquariums with plants. Lights 445 nanometers in royal blue are popular if you want to make your fish glow at night. It’s even possible to set up a group of LED lights in a way that fits your needs.

It’s easy to cover a lot of space in your tank with LED lights because they are usually set up in a strip.


Here are a few things to keep in mind when you use LED lighting in your aquarium:


There aren’t a lot of LED lights in aquarium kits that come with lights or lights in the hoods. Eclipse systems, for example, only come with fluorescent light bulbs. However, it’s still possible to change your Eclipse hoods into LED ones. Similarly, most light fixtures still come with fluorescent lights.

LED lights can be a little more expensive to buy at the start. You’ll have to spend more money initially, even though you’ll save money in the long run on energy and bulb replacement costs.

Another main weakness is in the use of planted tanks. Can only use Many LED lights for low to medium lighting needs. That will work well for most fish and some plants. The Kelvin ratings of 6500K to 7000K are the best for most plants in aquariums that have plants. When it comes to plants that need a lot of light, you’ll need to look for good LED lights.

A lot of new LED products are coming out all the time. Most experts agree that LEDs will be around for a long time.

Fluorescent tubes are suitable lighting to use in a fish tank. This type of lighting is excellent for aquariums.

The fish can also see more clearly from their aquarium lights. It helps fish to see other fishes and their food better. Light is essential for plants to thrive.

The lines don’t need to be changed often. It saves money. You can purchase Fluorescent tubes at a low cost, and they are straightforward to clean. Fluorescent tubes are bright enough to use.

Different spectrums are available for fluorescent lighting. There are three types of fluorescent light tubes: pink, blue, and white. While white lines can replicate the sun’s noon light, blue boxes will replicate the moonlight. The pink tubes can enhance the color of fish and improve plant growth.

How Fish Are Affected by Light. Fish don't need as much light like plants. If you have a fish tank, you can use incandescent or fluorescent lights, but you should be aware of the heat that incandescent lights can cause.

This, however, isn't true for LED lights. LED lights run much cooler than standard fluorescents and metal halides. They can change the colors and intensity of the lights, and they work well in both fish-only and plant tanks as long as you choose the right one.

It is best to turn off your aquarium lights when not in use because leaving them on all of the time may encourage algae growth in your tank.

Just as with human beings, most fish necessitate both periods of light and darkness in order to rest and regain their energy after spending the better part of the day swimming, searching for food, and potential mates.

According to our findings, algae grows best under white light and more rapidly under blue light than under red light. Consequently, our hypothesis is partially supported because the growth rate of the algae under blue light was higher than that of the algae under red light; however, the algae under control conditions experienced the greatest amount of expansion.
