To maintain a healthy and thriving aquarium, having the right filtration system in place is essential. One effective way to do this is by setting up a Refugium, which serves as a safe haven for beneficial microorganisms, plants, and algae. Among the various options available, one of the most popular choices for a Refugium is Chaeto algae, also known as Chaetomorpha.

Chaeto algae requires intense lighting to survive and grow. In particular, it thrives under high-intensity, LED-based lighting that includes both red and blue light spectrums. But with so many options on the market, it can be overwhelming to choose the right refugium light.

To help make your decision easier, I’ve done the research and compiled a list of the best refugium lights specifically designed for Chaeto algae. Whether you’re a seasoned aquarist or a beginner, these lights will help you achieve optimal growth and stability in your Refugium ecosystem.

Why Does Refugium Need Proper Lighting?

Chaetomorpha is basically a plant that you grow in your tank. Algae are vital for restoring a sustainable ecosystem, and their growth will clean the excess nitrate and ammonia in the tank water, keeping the fish safe and healthy. To promote algae growth, proper lighting is definitely very crucial.

Best Refugium Light For Chaeto Algae 1

Algae grow following a similar cycle and photosynthesis, and we all know how important role light plays in this cycle. Since sunlight is out of the question, you need to install artificial light of similar spectrums that is healthy for algae growth. Without proper lighting, the first step of photosynthesis will be hindered.

Can Chaeto Get Too Much Light?

You may think the more light, the better. But it doesn’t work that way. Chaeto needs at least 8 hours of darkness to rest them from photosynthesis. Constant light means constant photosynthesis and constant working. Even the trees get some rest when the darkness emerges. So why not your chaeto?

You should not leave the light on 24/7. Per day 16–18 hours of light is enough for the growth. For the best result, make sure to turn on and off the lights at the same time daily.

What Lights Are Best For Chaeto Algae?

Many companies offer different spectrums of light for algae growth. While all of them have different pros and benefits, the best lights are still blue and red. The red lights are the best option and primary spectrum for chaeto algae. More than 50% of red lights ranging from 630 to 700 nm are the best for any Refugium. For blue lights, 10-15% light with 435 to 495 nm wavelengths works best.

Final Words

Lights are indispensable in the Refugium for proper chaeto algae growth. Since sunlight is out of the equation, artificial light should be a priority. While choosing the lights, always remember it doesn’t have to be expensive. It only needs to be suitable for your Refugium, your demand, and the durability of the device.
