Keep reading to find out which refugium light will work best for you.
What is a Refugium Light?
A refugium tank is a smaller and different tank in an aquarium that helps filter waste and protect the nutrition-providing plants. It also helps provide food and reduce the presence of phosphate and nitrate in the aquarium.
A refugium light comes into the picture to help the macroalgae that live in an aquarium grow. Since macroalgae play a considerable role in controlling nutrients in the aquarium, the refugium light helps the macroalgae grow. In turn, it also works to help improve water quality and the overall living environment of the fish and plants in your aquarium.
If you’re confused about how a refugium tank works, think of the ocean for a second. Small fish and delicate plants often shelter themselves in certain parts of the sea to remain protected and safe from being eaten. In the same way, a refugium tank serves as a protective environment to keep fish and plants safe. When the refugium protects the plants, it helps nutrients and macroalgae grow in the aquarium. This is possible because the refugium and aquarium tanks share water but do not allow the fish to swim into the refugium.
Why Do You Need a Refugium Light?
You need a refugium light to help with the growth of macroalgae and the regulation of pH levels in the aquarium. When you let the light run for several hours at a time, the macroalgae grow more rapidly, which produces more significant amounts of oxygen. The oxygen is then released into the aquarium water and helps raise pH levels.
In other words, the refugium light helps strengthen the aquatic ecosystem and biodiversity within your aquarium.
Installing a Refugium Light
It is important to note that there are different types of refugium lights. You can suspend a few types of refugium lights outside the aquarium, while you can submerge a few types of lights in the water. If your aquarium is in a cramped space, it would be best to fit the light inside the tank.
When it comes to installing the refugium light, we would recommend reading the installation manual and instructions.
