It enables you to construct a sump refugium that successfully meets the needs of your aquarium. The sump refugium kit may be assembled with minimal effort and is simple to clean.


  • 3 cavities
  • Simple to set up


  • Excludes silicone adhesives and accessories.

Buyer's Guide

The sump pump or refugium should meet the requirements of the intended application. It must be watertight, constructed of high-quality materials, and large or small enough to support the water in the aquarium or pond.

The refugium must be sufficiently large and have enough chambers to produce the desired results. Typically, saltwater aquariums require a refugium system to prevent algae growth. Guarantee that the refugium is appropriate for the size of your aquarium to ensure that it functions properly.

Purchasing Advice for a Sump Pump and Refugium

  • Consider the product’s total price in relation to the product’s or kit’s power and accessories, and make sure it fulfills your budgetary needs.
  • Ensure that the sump pump circulates the appropriate amount of water based on the volume of the pond.
  • If you are purchasing a kit, the refugium should come with chambers. A conventional aquarium can be purchased and repurposed into a refugium, therefore it is not essential to purchase a refugium-specific tank if it lacks refugium chambers and accessories.
  • To ensure durability, the material should be waterproof and of good quality.


The VIVOSUN Submersible Ultra-Silent Pump is our recommendation for the best overall sump pump out of the models examined in this guide since it is both quiet and functionally convenient. If you’re searching for a choice that includes a protein skimmer, we recommend the Bubblefin Aquarium Sump Refugium DIY Kit due to its affordability and effectiveness in increasing water quality and eliminating algae via a complex system.
