10 Best Refugium Light For Chaeto: Review And A Complete Buying Guide

Best Refugium Light for Chaeto & Micro-algae

Good filtration is critical in a saltwater or reef tank, and here is where a refugium comes in handy. The addition of macroalgae or the storage of plants and coral in this mini-ecosystem can help complement the filtration in your main tank.

Refugium tanks are connected to the main tank; however, fish cannot swim between the two tanks since they are separated by a barrier. The vitamins and minerals that the ocean’s naturally protected plants add to the water’s quality make the identical setup in a refugium tank an excellent choice for saltwater or reef aquariums.

A refugium needs a lot of light to accomplish all of these tasks. For a refugium, it’s not as simple to select an aquarium light because the lighting needs to be both compact and powerful.

Microalgae and other organisms naturally regulate water levels and can be grown using specific lamps. To keep your plants and fish safe, you should use these lights to improve the water quality.

To assist you in discovering the best refugium light, we’ve reviewed a variety of lamps ideal for plants, coral, and fast-growing algae. So if you don’t have all the information you need, you won’t be able to find the right light for your tank.

What Is A Refugium?

Saltwater refugiums have grown in importance in recent years, particularly for reef aquariums. Refugiums are sections of filtration dedicated to biological filtration and the removal of nitrate and phosphate that are undesirable. Theoretically, this should help maintain the display tank’s characteristics more steady by preventing algae growth.

What Is The Purpose Of A Refugium?

There are several uses for refugiums, but the most common is filtering water or cultivating algae. But they can also house coral and plants. They can be utilized for breeding but not for storing fish.

You need to make sure the tank is full of macroalgae to employ refugiums for additional filtration. Again, a high-intensity light source is required to promote the growth of this algae.

Refugiums cannot be utilized as quarantine or hospital aquariums because they are connected to the main aquarium. On the other hand, a refugium can be a valuable place to temporarily shelter an injured or too territorial fish.

Why Do You Need A Refugium? 

Many saltwater enthusiasts might benefit from adding a refugium to their system because they can easily integrate one into their existing sump. Refugiums, like any other filtration, are designed to stabilize your tank and create an ideal environment for inhabitants.

Nutrient Export

When there are too many nutrients in tanks, such as nitrate and phosphate, and too much light, algae thrive. The growth of this algae is nutrient-limited, and it will only continue until the nutrients are exhausted.

It’s a fact of life that we all aquarists will have to deal with nuisance algae at some point. Likewise, reef-keepers must contend that these algae can swiftly encroach on their prized corals, making their tanks unbalanced and potentially damaging their equipment.

As long as we can control where this nutrient intake takes place in the display tank, algal growth isn’t a concern. In a refugium, you can use light and a more beneficial type of algae to achieve this.

pH Stability

The pH can also be controlled in a refugium. When the pH naturally decreases at night, the refugium lights are kept on to accomplish this.

When carbon dioxide is dissolved in acidic water, it becomes carbonic acid. Increasing amounts of carbonic acid are removed from the water by macroalgae, which raises the pH.

Your saltwater aquarium’s photosynthesis ceases to exist at night. Instead, fish, invertebrates, and other organisms capable of respiration are responsible for returning carbon dioxide to the atmosphere. Carbon dioxide cannot be converted to oxygen in the tank because there are no photosynthesizers.

This normal pH swing will not harm your fish tank’s inhabitants. On the other hand, some hobbyists prefer to keep their refugium light 24 hours a day to minimize pH fluctuations.

The ongoing growth of algae will result in the water’s pH level being buffered back to a healthy level.

Copepods, Amphipods, etc.

Live foods such as copepods, amphipods, and another microfauna can be grown in refugia. And many saltwater fish may benefit from a live food supplement.

Cleanup crew members-gone-bad who start picking corals, such as numerous crab species, can likewise be housed in refugia (as punishment). Fish fry can also be kept secure in refugiums while they grow.

Does A Refugium Need Light?

YES! You’ll need a high-intensity light source no matter what you intend to do with a refugium. The growth of your reef tank’s plants, corals, and macroalgae is aided by light.

What Kind of Light For A Refugium?

For macroalgae like Chaetomorpha to thrive in a refugium, you’ll need a lamp with a suitable wavelength of light. The Kelvin rating isn’t especially essential in this circumstance because the reading of yellow light in that spectrum is all that matters.

LED (Light Emitting Diode) lights for macroalgae should have a high concentration of red diodes to stimulate growth and a few blue diodes to maintain the density of a plant’s roots.

Light projections that include the violet and blue spectrums work best in a refugium for housing coral. In contrast to a full-spectrum light, a light mixture containing both of these colors is thought to be the most effective for enhancing coral growth and coloration.

How Much Light Does A Refugium Need?

The amount of light a refugium requires is determined by the tank’s intended purpose. Your main aquarium’s filtration system will benefit significantly from a high-quality refugium light, whether you’re using it to hold plants, coral, or both.

There must be a lot of macroalgae in your main aquarium because it is utilized for filtration. You’ll need a pungent bulb with a high light output to achieve this.

Types Of Refugium Lights

LED lighting is the most common sort of lighting in refugiums. However, there are a few additional options. Now, let’s take a quick look at several refugium lighting options.

Types Of Refugium Lights

LED Lighting

The most popular lighting option for a refugium is a LED lamp, which can produce a penetrating light with a constant color spectrum. In addition, LEDs have a longer lifespan and require less maintenance than fluorescent lights. Another advantage of LED bulbs is that they produce very little heat, so you don’t have to worry about overheating your tank.

This light has a small footprint and may be utilized in various aquarium setups, including planted tanks. A wide range of options is available, from slimline strips to clip-on units to spotlights. Moreover, they are available in a wide variety of color palettes.

Fluorescent Lighting

Fluorescent bulbs are commonly used with reflectors because they distribute more light into the tank. Green and yellow wavelengths are eliminated from this lighting to produce the desired spectrum, including red and blue light (marine) and bulbs that simulate daylight.

Long T8 or T5-tube fluorescent lamps are the most common, but longer life and more compact size make T5 bulbs the preferred choice. They’re also more intense.

Fluorescent lights produce a lot of heat. So, a chiller is frequently used in conjunction with a fluorescent bulb to maintain a consistent temperature in a fish tank. However, the bulbs don’t provide a uniform color spectrum in the long term, necessitating frequent replacement.

Metal Halide Lighting

For the most part, metal halide lamps offer minimal operating costs and a long lifespan. Regrettably, this form of light generates a lot of heat and is highly costly.

This lighting is incredibly intense and closely resembles natural sunshine, so it’s ideal for a reef tank or a planted aquarium. Metal halides (metal compounds containing iodine or bromine) and mercury vapor are used in the bulbs.

    Buying Guide For Best Refugium Light

    Before purchasing a refugium light, there are a few things to consider. All of these topics will be briefly addressed in the section that follows.

    Buying Guide For Best Refugium Light

    Tank Size

    It is crucial to consider the size of your tank while choosing LED lighting for your aquarium. For smaller refugiums, some species are better adapted, and for a refugium with hundreds of gallons of water, some are ideal. 

    Ensure that the light you choose is appropriate for your aquarium’s size. There is a fine line between too much intensity for smaller tanks and too little power for larger tanks.

    Intensity

    Light wattage, tank depth, and the distance from the top of the water to the light source are all factors to consider.

    For the growth of aquatic plants and macroalgae, adequate light is essential. Three factors influence light intensity. Low light intensity and a deeper tank will not help your macros grow.

    Spectrum

    The wavelengths of different hues are different. For example, the light spectrum in your refugium water comprises three distinct wavelengths.

    Consider purchasing those with blue light because they can reach your marine plant’s roots at the deepest levels.

    Light Distribution

    Regardless of the size of your refugium, you must use a lamp that can equally distribute the light. Phosphate and nitrate levels will rise if macros are hindered by an uneven distribution.

    Mounting Options

    The mounting choices for Refugium lights are numerous. Poorly-fitting lights are not worth the money, even if they are of good quality. To prevent the collapse of your entire refugium system, you must set the light at a specified distance from the other components. As a result, keep this in mind prior to making a purchase.

    Easily Of Install

    It’s a lot more challenging to use and set up anything that requires a lot of effort. Refugium lighting is no different in this regard. Therefore, you should look for an easy-to-install device. In addition, look for one with a lengthy power wire that can readily attach to the plug.

    Timer

    Your individual refugium configuration necessitates a precise amount of light with a fixed time duration. So there should be a timer for the Refugium light. 

    For example, if you need 12-14 hours for coral reef and algae growth and don’t have a timer in your light, it will stifle growth by hurting reefs and macros. In addition, a timer can mimic the dawn and sunset patterns by adjusting the brightness of the light, which is an attractive feature.

    Controllability

    You can remotely change the color, timing, and intensity without getting too close to the tank using a high-tech light unit. Apps put on your smartphone will allow you to operate it. As a result, go for a light that is easier to maneuver.

    Heat Management

    A refugium lamp that doesn’t have a sufficient heat management mechanism may not last as long as it should in the long run. Adding a fan-driven cooling system with this light would be fantastic. But don’t sacrifice other characteristics to get these. Make a well-informed choice.

    Waterproof

    A good refugium light has another fantastic attribute. Any water-resistant light is less likely to be destroyed by water contact. On the other hand, if your light is not waterproof, any mishap could cause it to malfunction.

    Best Wavelengths For Growth And Water Penetration

    Even if you don’t have a background in science, you should be familiar with the concept of wavelength. The color of the refugium depends on the plants in the tank and the depth of the water.

    First and foremost, you should establish a list of the different kinds of plants and coral in your refugium. What follows is an investigation into the native habitats of the plants you’re interested in.

    Aquarists commonly utilize green macroalgae like Chaetomorpha in their refugia, and Chaeto plants are most likely to be exposed to red wavelengths in the forest or natural water bodies because red wavelengths have the lowest penetration levels. Therefore, when looking for an LED light system, go for one with a red wavelength to help the Chaeto plant’s development.

    Water Penetration Level

    ColorWavelengthPenetration Depth (Meter)
    Blue380-490 nm57-61
    Green490-575 nm43-50
    Yellow575-585 nm27-32
    Orange585-650 nm13-16
    Red650-780 nm3-6

    When viewed through water, red light has a limited ability to penetrate while blue light has the highest depth of penetration. Refugium tanks with good marine plant populations necessitate a light penetrating deeper into the water column.

    FAQs

    How To Install A Refugium Light?

    The parts and accessories that make up a refugium light are unique, so their installation procedures will differ. 

    If you run into any issues, you can always refer back to the handbook for installation. In addition, the refugium forum and the manufacturer’s website are good places to look if you can’t figure out what’s going on.

    The most important thing to remember when installing your light is to keep your plants at a safe distance from the light fixture you’re installing.

    Next is to connect your electric supply, which we’ll do next. Set up at an area where you can connect your cord since some light sets have long cables and others have small ones.

    How Long Should You Leave Refugium Lights On For?

    A minimum of ten or twelve hours of bright light per day appears to be the minimum need for planted refugia. However, some aquarists leave their lights on 24 hours a day, seven days a week, with no apparent harm.

    Can You Grow Chaeto With White Light?

    Yes, the white light will aid Chaeto’s growth. As a result of the fact that it contains a variety of colors, such as red, orange, blue, and green.
