Why is the Synergy Reef Shadow® Overflow the BEST Overflow for your Aquarium.

What is an Overflow Box?

An overflow box serves the purpose of draining water from your display aquarium into your aquarium sump or filtration system. It typically comprises a weir and drainpipes designed to efficiently redirect water out of your tank and into the sump. The installation of overflow boxes can be undertaken either by the aquarium manufacturer or as an aftermarket addition by the end user.

Overflow boxes come in two main types: internal and external. An internal overflow box is situated inside the aquarium, often built by the tank manufacturer. However, these internal boxes can be large and bulky, occupying valuable space within the aquarium. In response to this, there has been a shift towards external overflow systems, which are located outside the aquarium. This design choice allows for more space within the aquarium, promoting a cleaner and less obstructed aesthetic.

An excellent example of an external, low-profile overflow system is our Shadow® Overflow, which not only effectively drains water but also minimizes the impact on the overall appearance of your aquarium and is virtually silent.

The Shadow® Overflow is a self install kit that allows anyone to add an overflow system to virtually any aquarium themselves. Whether you are having a custom aquarium built or want to buy one at a local pet store, you can use the Shadow® Overflow for your tank!

Why the Shadow® Overflow was developed?

More than 15 years ago, Synergy Reef embarked on a journey to revolutionize the aquarium industry by developing an overflow system that catered to the discerning needs of avid hobbyists. Our goal was to create a system that embodied the following key attributes:

  1. Small Footprint in the Aquarium: We prioritized a design that minimizes space consumption within the aquarium, ensuring a sleek and unobtrusive presence while maximizing the aquatic display.
  2. Low Noise Levels: Recognizing the importance of a tranquil aquatic environment, we focused on crafting an overflow system that operates with minimal noise, allowing enthusiasts to enjoy their aquariums without disruptive sound interference.
  3. Ease of Installation: Streamlining the installation process was a core objective. Our aim was to provide hobbyists with a user-friendly system that facilitates straightforward setup, ensuring a hassle-free experience from the outset.
  4. Ease of Maintenance: Acknowledging the significance of aquarium maintenance, we aimed to develop an overflow system that simplifies the upkeep process. Easy access and uncomplicated maintenance procedures were integral to our design philosophy.

Through years of dedication and passion, Synergy Reef has endeavored to meet and exceed these criteria, resulting in an overflow system that enhances the overall aquarium experience for hobbyists worldwide.

The History of the “Ghost” Overflow

Driven by a discerning need unmet by existing market offerings, Rick Lowe embarked on a rigorous journey to conceive and develop a proprietary overflow solution. Over an intensive period of 2-3 years dedicated to research and development, he successfully crafted a design that impeccably aligned with our specific requirements for an overflow system.

In 2013, we proudly introduced the inaugural version of our overflow, aptly named the “GHOST,” tailored for Reef Savvy. This momentous release marked a collaborative effort showcased at MACNA (Marine Aquarium Conference of America) 2013 in Miami, underscoring our commitment to innovation. The Ghost, originally a substantial 24″ wide overflow, demonstrated commendable performance for a BETA product, yet Rick Lowe identified areas for enhancement. Here is a article that was written about that first “”Ghost Overflow” that we designed and built https://aquanerd.com/2013/09/reef-savvy-ghost-overflow.html

Contrary to conventional wisdom favoring larger overflows, we recognized that they fell short of our paramount criterion: maintaining a “Small Footprint in the aquarium.” Simultaneously, our Synergy Reef 16″ overflow made its debut at MACNA 2013, with Rick proudly presenting the first prototype (See Photo below). In a strategic decision, we amicably parted ways with Reef Savvy, redirecting our focus towards refining our proprietary overflow design and engaging directly with our customers to provide the best experience.

Centered on perfecting the smaller 16″ version, we unveiled the “16” Synergy Reef Overflow” in 2014, embodying a culmination of our dedication to precision engineering. We no longer produced the 24″ Ghost, as we knew the overflow could be smaller with the same performance. Concurrently, we expanded our product line to include a 20″ Synergy Reef Overflow equipped with 1.5″ drains, catering to larger tanks and optimizing flow dynamics.

The Shadow® Overflow was born!

Moving Forward to 2016: The Birth of the Shadow® Overflow

Now, let’s fast forward to 2016. After putting our 16″ Synergy Reef Overflow through over 5 years of rigorous testing and with over 2000 units in service, we decided it was time to up the ante. We teamed up with tool designers and fluid dynamic engineers to create something special – the Shadow® Overflow. Instead of the old-school method of handcrafting and gluing flat acrylic stock together, we switched to using injection molds. This process makes parts that fit together perfectly, bringing a whole new level of precision to our overflow systems. This also allowed us to design components that you cannot build with flat acrylic pieces.

Distinguishing the Superiority of the Synergy Reef Shadow® Aquarium Overflows

While it may seem that all aquarium overflows share the common function of draining water from the display into the aquarium, it is crucial to recognize the significant disparities among them. The success of our renowned Shadow Overflow has led to the emergence of numerous imitations in the market. Although these copycat products may bear a visual resemblance, it is imperative to emphasize the substantial differences in their design, build quality and performance.

We deliberately refrain from association with major online retailers, as our commitment extends beyond mere profit considerations. Our observation reveals that these platforms often prioritize financial gains over delivering the finest products to customers. Unfortunately, many “Copy Cat” products flood these online marketplaces, jeopardizing the authenticity and quality that discerning hobbyists deserve.

In our unwavering pursuit of excellence, we have chosen a distinct path. By selling directly to you and through a carefully selected group of resellers, we ensure that you receive the absolute best aquarium overflow at the most competitive price. This commitment is grounded in our dedication to providing aquarium enthusiasts with a superior and authentic product, transcending the compromises often associated with copycat alternatives.

Now, let’s talk about the Shadow® Overflow itself. While there are different types of overflow systems out there, like Durso, Herbie, and Bean Animal, we’ve taken a unique approach. We like to call it a “Modified Full Siphon,” borrowing bits from a few different methods, especially the Bean Animal. It’s similar but with our twist, optimizing how it works for your aquarium. And here’s the kicker – the Shadow Overflow is a universal overflow that can be configured in any of the above setups. It’s all about giving you the flexibility to make it work seamlessly with your aquarium.

The Shadow® Overflow has been through a few version changes since it’s introduction. We have made some major changes the the initial design and have made it even better. We are currently on V3 which can be found here Synergy Reef Shadow V3 Overflow

Navigating the Transition: From Freshwater to Saltwater Tanks

For those entering the realm of saltwater aquariums from the familiar terrain of freshwater tanks with their conventional setups, there’s a noteworthy shift in the dynamics. Setting up a saltwater tank involves nuances beyond the obvious distinctions, and one significant departure lies in the prevalent use of an overflow and sump system.

Unlike freshwater tanks where equipment is either contained within the tank or hangs on the back, saltwater tanks often employ an overflow and sump configuration. While this might seem like Captain Obvious pointing out the obvious, the differences extend beyond the surface.

In the context of saltwater setups, a sump is essentially an additional tank positioned under or away from the primary tank. It serves as a dedicated space for housing most of the equipment essential for the operation of the main display tank. Though smaller in size compared to the primary tank, the volume it contributes adds to the overall stability of the entire system.

The overflow, aptly named, is the mechanism through which water is drawn from the main display tank and directed into the sump. This is typically achieved by allowing water to overflow in a controlled manner, facilitating its transfer to the sump. Embracing this overflow and sump system in saltwater tanks brings about subtle yet impactful variations that contribute to the unique character of these aquatic environments. Our Shadow® Overflow is the industry standard in aquarium overflow systems. You can find more information about the Shadow® Overflow here.

Aquarium Basics 101 – Nitrogen Cycle, What is it?

The nitrogen cycle is a process that occurs in all aquariums, and it is essential for maintaining the health of the fish and other organisms living in the aquarium. This document will explain the “Cycle” and how it works.

Fig.A1 – Full Nitrogen Cycle

NH3 (ammonia) to N02 (Nitrite)

The nitrogen cycle begins when fish produce waste in the form of ammonia. Ammonia is toxic to fish and must be removed from the water. Bacteria called nitrosomonas (Fig.A2) convert the ammonia (Figure A.2 – Steps 1 to 2) into nitrite, which is also toxic to fish.

Nictrosomonas Fig .A2

The nitrogen cycle is important because it helps to break down the harmful waste produced by the fish and other organisms in the aquarium, making it safer for them to live in. It is essential to establish the nitrogen cycle in a new aquarium before adding fish to it, as the fish will produce waste from the moment they are introduced to the aquarium. This can be done through a process called “cycling” the aquarium, which involves adding a small amount of fish or using a product called a “cycle starter” to provide a source of ammonia. There are many different companies that make these cycle starter products. The bacteria that convert the ammonia and nitrite will then grow and establish a colony, allowing the nitrogen cycle to begin.

N02 (Nitrite) to N03 (Nitrate)

After nitrite is produced in an aquarium, it is then converted into nitrate by a type of bacteria called nitrobacter. (Fig.A3) Nitrite is toxic to fish and must be removed from the water to maintain the health of the fish and other aquatic life in the aquarium. Nitrobacter bacteria are found in most healthy aquariums and play an essential role in the nitrogen cycle by converting the toxic nitrite into the less toxic nitrate.

Once the nitrite is converted into nitrate (Fig.A1 – Steps 3 to 4), it can then be removed from the water through regular water changes. Nitrate levels that are too high can also be harmful to fish and other aquatic life, so it is important to monitor nitrate levels and perform regular water changes to keep them at a safe level. In a healthy aquarium, the nitrogen cycle will continue to process the fish waste, maintaining a balance between ammonia, nitrite, and nitrate and helping to keep the water clean and safe for the fish and other aquatic life.

Nitrobacter FigA.3 – Another type of bacteria called nitrobacter convert the nitrite into nitrate, which is less toxic to fish and can be removed through regular water changes.

How to remove Nitrate (N03) from your system.

There are a few different methods that can be used to remove nitrate from a marine aquarium, including:

  1. Water changes: Regularly performing water changes can help to reduce the nitrate levels in your aquarium. By replacing some of the water in your tank with fresh, clean water, you can dilute the nitrate concentration.
  2. Nitrate-removing media: There are several types of nitrate-removing media available for use in aquarium filtration systems, such as denitrifying filters or nitrate-removing resins. These can be effective at removing nitrate from the water.
  3. Live rock and macroalgae: Live rock and macroalgae can be used to naturally remove nitrate from the water. These organisms are able to take up nitrate and use it as a source of food, reducing the nitrate levels in the water.
  4. Nitrate-reducing bacteria: Certain types of bacteria can be used to convert nitrate into nitrogen gas, which can then be released into the air. This is known as denitrification and it can be done in a denitrification filter, also called a deep sandbed, can be added to the filter system.
  5. Algae turf scrubbers : this device uses algae to absorb nitrate in the water and it is a natural, efficient and low maintenance way to remove nitrate.
  6. Macro Algaes : using different macro algae in a refugium is also a very effective way to remove Nitrates. This does require removing or cultivating the algae as it grows, as to not allow the nitrates to be reintroduced into the aquarium.

It’s important to note that it’s not always necessary to completely eliminate nitrate from your marine aquarium, as some nitrate is required for the growth of beneficial microorganisms in the tank. Typically, a nitrate level of 20-40 ppm is considered acceptable in a marine aquarium.

It is also important to address the cause of high nitrate level, to prevent it from happening again, overfeeding, overstocking, lack of maintenance etc.

Water Changes – The most effective way to remove N03 (Nitrates) (Fig.A1 – Steps 5)

Water changes are a simple and effective way to remove nitrate from a marine aquarium. The basic idea is to replace some of the water in the tank with fresh, clean water. This dilutes the concentration of nitrate in the tank and can help to reduce nitrate levels over time.

To perform a water change, you will need to have a separate container of clean, pre-mixed saltwater that matches the temperature, salinity, and pH of your tank. It is recommended to use a good quality water conditioner to remove chlorine and chloramines from tap water, if you use tap water as a source.

Here are the general steps to perform a water change:

  1. Turn off any equipment, such as pumps or filters, that may disturb the water or the inhabitants of the tank during the water change.
  2. Use a clean and dedicated siphon or pump to remove some of the water from the tank, typically about 10-20% of the total volume depending on the nitrate level and the size of your tank, it could be more or less.
  3. Add the pre-mixed clean water to the tank, to replace the water that you removed.
  4. Keep an eye on temperature and salinity level, use a hydrometer or refractometer to make sure the new water matches the tank’s water.
  5. Once the water change is complete, turn the equipment back on and observe the tank for a few minutes to make sure everything is running smoothly.

It’s important to do water change regularly and consistently. A good schedule can be once a week or every other week, depending on the size of the tank and the bioload it has. Keep in mind that more frequent water changes will be necessary in tanks with high nitrate levels, or if there are a lot of fish or other inhabitants in the tank.

Also it’s important to use a good water test kit, to keep an eye on the nitrate level before and after each water change, this will help you determine if the changes you are making are effective and if more is needed to be done.

Macro Algae – Refugium – Another effective way to remove N03

There are several types of macroalgae that can be used to remove nitrate from marine aquariums. Some of the most commonly used types include:

  1. Caulerpa: This type of macroalgae is available in several different varieties and can grow quickly in a variety of lighting conditions. It is also able to take up nitrate and other nutrients from the water, making it an effective choice for removing nitrate from a marine aquarium.
  2. Chaetomorpha: Also known as “spaghetti algae,” chaetomorpha is a type of green macroalgae that is known for its ability to remove nitrate, phosphates, and other nutrients from the water. This algae is a very good option if you are looking to address high levels of nitrate as well as other issues like phosphates.
  3. Red Macroalgae: Such as Gracilaria and Hemprichii, These macroalgae species are also known for their ability to absorb nitrate from the water and are also a good alternative for those looking for a more decorative option for their aquarium.
  4. Halimeda: This is a genus of calcareous green macroalgae, it is slow-growing but effective in removing nitrates from the water and can also help to maintain proper pH levels in the aquarium.

It’s important to note that some of these macroalgae can be invasive, and if they grow too much or get out of control, they can actually contribute to nitrate problem, but this can be controlled by pruning and keep a healthy balance between the algae and the other inhabitants of the tank.

It is also important to have a proper lighting and flow to support the growth of these macroalgae, and to make sure that you don’t have any herbivorous fish or invertebrates in the tank that will eat them.
