Aquarium Sump / Refugiums

What is a aquarium Sump?  What is a Refugium?  What is the difference between the two?  Do I need or want one in my tank?

These are the questions I hope to briefly answer for you here.  A “Sump” is an area set up below the tank that water enters into from the tank and is usually filtered there before being pumped back up into the tank.   The aquarium sump is generally considerably smaller than the main tank.  A 20g sump would be adequate for say a 75g tank for example.  A sump filtration system is more or less like an open canister filter.  This gives it flexibility that a canister filter doesn’t have.  For example, you can put the heater in the sump and add things like a protein skimmer or phosphate or other reactors.  Also, you can use common filtration materials instead of proprietary filter medias that you often need to use with canister filters.

The term “Refugium” typically refers to a sump specifically set up to harbor plant or animal life that is distinct from the tank.  A lot of aquarists will add a few plants and a light to the sump area which will help clean the water.  However, this doesn’t do a very thorough job of removing nutrients and nitrates so a dedicated nitrate reactor like the Aquaripure will work a lot better.  Still, some aquarists have fish that will eat or not allow plants in the aquarium so they want some in the sump.  A sump will provide the flexibility to do this if you wish.  Sometimes the terms “refugium” and “sump” are used interchangeably but the actual equipment itself that is used can be set up either way.  From here on I will refer to the equipment as “aquarium sump.”

Aquarium sumps are usually used for larger tanks, generally 75g or larger although they can be used on smaller tanks.  A lot of aquariums will have plumbing in them to set up a sump and it is easy to drill acrylic tanks to set up a sump.  Even if you have a glass aquarium that is not pre-drilled, you can use an overflow box and custom return hose to very closely emulate the function of the pre-drilled holes and configuration.  If you have a pre-drilled tank and need the sump plumbing I have that here.  All of these items are found in the Other Aquarium Sump supplies category.

The water rises 10 inches , but enters the next chamber 4 inches from the bottom. 2. The second chamber is the refugium chamber itself. This is where live sand, rock, macro-algae etc. is added. Most people also put a light over this section to stimulate growth and the refugium environment. 3. As the water rises to the 10 inch high mark, it spills over and enters the bubble trap chamber. This can hold grating and filter media.This over-under chamber helps disperse bubbles from the skimmer. Some people add bioballs to this area to help break up the bubbles. 4. The water enters the final chamber through the bottom opening and into the return chamber. This is where the return pump sends the water back to the aquarium. Most people use submersible pumps and send the water back through the top. A bulkhead can be added for external pumps also. The unit is guaranteed against manufacturing defects and leaks for 3 years.
