What Is a Reef Sump?

Before buying a reef sump, you need to know what it is. A sump is a container that goes behind or beneath an aquarium. It holds the water and gives you a place to store equipment that the system needs.

A reef sump can be made of acrylic and glass. It can also be made of food-grade plastics or livestock feeding troughs. The material chosen depends on how much space is available.

Usually, you need a glass or acrylic tank if the sump must go under the aquarium. If the sump is in the basement or has plenty of space, stock tanks are suitable. The container type should be considered as well as the sump.

Benefits of a Sump for Reef Tank

A reef tank sump has many advantages. It is helpful to learn about the benefits, so you understand why you need a sump.

Pollutants in the tank accumulate in the water. A sump slows that issue and increases total water volume. The sump also skims the water’s surface, giving you clear water.

Sumps also work well to lower the water temperature by up to two degrees Fahrenheit. This can help your reefs thrive and grow.

The sump also hides your equipment. This can include protein skimmers, heaters, and monitoring probes. You can also move more equipment to the sump and out of the display area.

With a sump, you get more consistency with water levels. Your display tank maintains the right water level regardless of the time. Evaporation does occur in the sump.

Most aquariums need additives to help the water. You can pour the additives directly into the sump. This allows the chemicals and RO/DI water to mix well before it enters the tank.

What to Put in Reef Sump?

Many people are new to reef aquariums and wonder what to put in them. Some aquarists only use a heater and skimmer in their sumps. Others like to put sand, live rocks, and other critters.

It is best to put in about four inches of sand at the bottom of your sump. You also want to include macroalgae to help clean the tank between water changes. You are also going to have your reef.

Sometimes, aquarists put Chaetomorpha in the tank as it reduces nitrates in the water. Live rock is also helpful because it offers shelter for organisms and pods.

You are also likely to have a return pump to continue circulating water.

There are no rules about what you can put in your sump. However, some enthusiasts claim that you should not use activated carbon.

The carbon depletes trace elements that are needed in the aquarium. Carbon can absorb some metals in the water, but it works better for organic compounds. The protein skimmers you use in the tank also remove trace elements in the aquarium.

Therefore, you may not want to include carbon and other chemicals all the time. Many aquarists believe you should only use carbon if the water isn’t clear. However, with the right reef sump, you should always have clear water.

How to Setup a Reef Sump?

Once you buy the reef sump, you must set it up correctly. Otherwise, your livestock will die, or the water will turn brown. If you already have your tank set up with livestock, you can still buy a reef sump and set it up.

The tank might be on a stand, which might be difficult to remove. You should buy a sump designed for your size tank. The sump should be the same length and two inches shorter than your tank.

Most sumps have a section for a refugium, skimmer, return zone, and top-off compartment. The sump is likely to take up most of the room in the stand. That is the goal of the sump.

If you have old equipment that you’d like to use with the new sump, you should clean them thoroughly and rinse them well. However, the sumps reviewed here have all the tools you need.

You might want to put foam beneath your sump to prevent pressure points that could cause failure. Depending on the connections, you might have to drill holes into the stand. Some people think it is easier to build the stand around the sump.

Once the sump is in the place where it is going to sit, you should install the Kent valve and connect the RO/DI feature. You can now add water to your reservoir.

While most sumps have the RO/DI system integrated into the sump, it might not be best. You can set up a top-off container beside the sump. This limits the amount of freshwater that can be added at one time.

Once the top-off container is full, you can close the ball valve from the RO/DI unit. You can open the ball valve the next time you refill the compartment. If you choose the top-off container, it should handle your tank’s needs for 48 hours.

Refilling it should only take 45 minutes. It is advised not to leave your RO/DI unit on all the time. It only needs to run about four hours each week.

The RO/DI unit keeps your top-off section filled. When the aquarium needs water, the float sensor is activated.

The top-off pump adds more RO/DI water into the skimmer section. This step replenishes evaporated water.

You should attach the device and the sensor in the return section of your tank. It can be secured with zip ties.
