Why Hang On Back Refugium is Necessary for my Tank

As a long-time aquarium enthusiast, I have learned the importance of maintaining a healthy and balanced ecosystem within my tank. One crucial component of this is the use of a hang on back refugium (HOB refugium). This simple yet effective device has become a staple in my tank maintenance routine and has greatly improved the overall health and stability of my aquarium.

One of the main reasons why an HOB refugium is necessary is its ability to provide additional filtration. The refugium serves as a secondary filter, which helps to remove excess nutrients and pollutants from the water. This not only keeps the water quality optimal but also reduces the frequency of water changes, making it easier to maintain a healthy environment for my fish.

Furthermore, the HOB refugium also acts as a natural algae scrubber. It provides a safe haven for beneficial microorganisms such as copepods and amphipods to thrive, which in turn helps to keep algae growth under control. These tiny creatures serve as natural cleaners by consuming excess nutrients and algae, preventing them from overgrowing in the main tank.

Another significant benefit of having an HOB refugium is its ability to increase biodiversity within my tank.

My Buying Guide on ‘Hang On Back Refugium’

As an experienced aquarium hobbyist, I have come to learn the importance of having a refugium in my tank. A refugium is a separate tank or compartment connected to the main aquarium, used for various purposes such as filtration, breeding, or growing macroalgae. And when it comes to easy and efficient refugium setup, hang on back (HOB) refugiums are my go-to choice. In this buying guide, I will share my knowledge and experience on purchasing a hang on back refugium.

What is a Hang On Back Refugium?

A hang on back refugium is a compact and convenient way to add a secondary tank to your existing aquarium. It is designed to be mounted on the back of your main tank, hence the name “hang on back”. This type of refugium uses the water from your main tank and gravity to function, eliminating the need for additional pumps and plumbing.

Why Do I Need a Hang On Back Refugium?

There are several reasons why having a hang on back refugium can greatly benefit your aquarium.

  • Filtration: A HOB refugium serves as an additional filtration system for your main tank. The macroalgae and live rock present in the refugium help remove excess nutrients such as nitrates and phosphates from the water.
  • Breeding: If you have small fish or invertebrates in your main tank that are at risk of being eaten by larger ones, you can transfer them to the refugium for protection.
  • Macroalgae Growth: A HOB refugium provides an ideal environment for macroalgae growth. These plants absorb harmful chemicals from the water while producing oxygen.

What Should I Consider Before Buying a Hang On Back Refugium?

Before making a purchase, there are a few factors that you should consider:

  • Tank Size: The size of your main tank will determine how big or small of a HOB refugium you can get. Make sure to measure the space available on the back of your tank before buying.
  • Capacity: Consider how much water volume you want in your HOB refugium. This will depend on what you plan to use it for – filtration or breeding.
  • Budget: HOB refugiums come in various price ranges. Set a budget beforehand so that you can narrow down your options without overspending.
  • Type of Macroalgae: Some HOB refugiums come with live macroalgae included while others do not. Decide if you want to purchase one with live macroalgae or if you prefer starting with dry rock and growing your own algae.

Tips for Maintaining Your Hang On Back Refugium

To keep your HOB refugium functioning properly and prolong its lifespan, here are some tips:
