The Benefits of Sump Refuges

Published on 1 March 2022 at 15:08

In an aquarium, sump refugiums are a good choice to help manage nitrogen levels. They can serve a variety of purposes, from centralized equipment to the promotion of targeted plant or animal growth. These tanks are often accompanied by live rock rubble that provides extra surface area for bacteria to colonize. However, a sump that is too deep for the intended use may have problems with oxygenation and toxicity.


A refugium must have adequate lighting, so it should be switched on even when the main aquarium is off. It also needs to be monitored to ensure that the water level remains stable. It is important to choose a light that will best match the environment of the refugium. Harvest macroalgae when necessary and feed crustaceans and amphipods as well. Having a fuge on your sump is a great way to improve the conditions of the main tank and will make maintenance a breeze.


A fuge doesn't need to be complex. It can be as simple as a separate tank or even a Rubbermaid container. Either way, a fuge offers many benefits for your system. If you are looking for a cheap, simple solution, a fuge could be the answer. They can also be part of your sump or separate chambers. If you are not sure, consider adding a fungus bioreactor to your system.
