The Need for an Aquarium Sump

An aquarium sump refers to an external water tank that connects to the primary tank using inflow and outflow water pipes. Its main function is to increase the capacity of water in your aquarium and provide a centralized point of operation for your filtration equipment. It enables you to distribute nutrients and supplements to your aquarium. Aquarium sumps are common in reef and saltwater aquariums. They can also be used in freshwater aquariums.

Increase in Water Capacity

Regardless of the type of aquarium, the sump plays a major role in increasing the water capacity.  The high capacity inhibits the build-up of nitrates and ammonia, which pose a dangerous threat to the fish. It also ensures that the PH and temperature levels of the water become more stable, creating a thriving environment for your fish.

An aquarium sump is often smaller than a display tank. Its water capacity is almost half that of the primary tank. You should choose one that can be placed as close to the primary tank as possible. When setting up an aquarium, ensure that you have enough space in case you decide to install an aquarium sump in future.

Setting it Up

Setting up an aquarium sump from requires you to move the filtration system from the display tank to the sump. As the water from the display tank flows to the sump, it passes through a filter that removes all the debris and accumulates it for elimination. You can also install protein skimmers in the sump to prevent the build-up of toxins and minimize formation of foam. Before releasing the water into the primary tank, you can also run it through a chemical filtration agent like zeolite or carbon. You can even decide to grow some algae in the sump to lower the nitrate levels in the water.

Having a central place to do all this work makes it easy for you to manage your aquarium. The sump makes a perfect central place to determine what goes on in the display tank. When adding supplements and nutrients to the aquarium, take into account the main tank and sump tank capacities and use them to determine the correct ratios.

In Closing

From what we have discussed, it is clear that improved filtration is one of the advantages of having an aquarium sump. You will also benefit from increased stability and better aesthetics. For smaller freshwater and saltwater aquariums, you have to consider the cost and convenience of installing and maintaining the sump. In case you want to install an aquarium sump, take some time to understand the technical requirements of operating one. If you are sure that you can maintain one, proceed and install it next to your display tank.
