Why I Believe Hang On The Back Refugium is Necessary

As an avid aquarium owner, I have come to learn the importance of having a hang on the back refugium in my setup. A hang on the back refugium is essentially a small compartment attached to the back of an aquarium that serves as a secondary filtration system. While some may view it as an optional addition, I believe it is necessary for several reasons.

Firstly, a hang on the back refugium provides a safe haven for beneficial microorganisms to thrive. These microorganisms contribute greatly to the overall health of the aquarium by breaking down harmful toxins and maintaining water quality. Without a refugium, these microorganisms may struggle to survive in the main tank due to competition with fish and other organisms.

Secondly, a hang on the back refugium helps to control algae growth in the main tank. Algae can be a nuisance in any aquarium and can quickly take over if not kept in check. The presence of macroalgae in the refugium helps absorb excess nutrients from the water, thereby reducing algae growth in the main tank.

Another important reason why I believe hang on the back refugiums are necessary is because they provide additional space for

My Buying Guide on ‘Hang On The Back Refugium’

As an avid aquarium enthusiast, I have found that a hang on the back (HOB) refugium is a great addition to any tank. It not only adds to the aesthetic appeal of the tank but also serves as a functional and beneficial component for the overall health of your underwater ecosystem. If you are considering purchasing a HOB refugium, here are some important factors to keep in mind:

Size and Capacity

The first thing to consider when buying a HOB refugium is its size and capacity. You want to make sure that it is suitable for your tank’s size and can accommodate the amount of water flow that your tank requires. A general rule of thumb is that the refugium should have a volume of at least 10% of your main tank’s volume.

Material and Durability

The material used in making the refugium is also an important factor to consider. Most HOB refugiums are made from either acrylic or glass. Acrylic is more lightweight and durable, while glass is heavier but less prone to scratches. Whichever material you choose, make sure it is of high quality and can withstand constant exposure to water.

Design and Functionality

HOB refugiums come in various designs, but the most common ones have two chambers – one for macroalgae growth and one for housing beneficial organisms such as copepods and amphipods. Some models also have built-in protein skimmers or media baskets for additional filtration purposes. Consider your specific needs when choosing the design that best suits your tank.

Water Flow

Proper water flow is essential for a successful HOB refugium setup. Make sure that the model you choose has adjustable flow rates or comes with a pump suitable for your tank’s size. The ideal flow rate should be around 10-20 times the volume of your refugium per hour.

Price and Brand Reputation

HOB refugiums come in various price ranges depending on their size, features, and brand reputation. It may be tempting to opt for cheaper options, but investing in a reputable brand with good reviews will ensure better quality and longevity.

Maintenance

Like any other component in your aquarium, regular maintenance is crucial for the proper functioning of a HOB refugium. Look for models that are easy to clean and maintain, with accessible chambers for harvesting macroalgae or cleaning out debris.

In conclusion, investing in a HOB refugium can greatly benefit your aquarium’s overall health by providing extra filtration, nutrient exportation, and biodiversity enhancement. When considering purchasing one, keep in mind its size, material, design, functionality, water flow rate, price range, brand reputation, and maintenance requirements to ensure you get the best fit for your specific needs. Happy shopping!
