Introduction to the AquaVitro Element™ Series
The AquaVitro Element™ series is designed to provide versatile, efficient, and user-friendly filtration and supplementation solutions. The series includes:
- Element M Media Reactor – a multi-functional filter media reactor
- Element Z Zeolite Reactor – specialized for nutrient reduction using zeolite
- Element Ca Calcium Reactor – maintains calcium, alkalinity, and magnesium levels for reef success
Each reactor is engineered to optimize performance with innovative features such as adjustable flow, internal media separation, and CO2 recycling. Let’s begin by examining the Element M Media Reactor in detail, as it is the foundation of the series and a versatile tool for any aquarium setup.
The AquaVitro Element M Media Reactor: Versatility and Efficiency in Filtration
The AquaVitro Element M Media Reactor is a high-performance filter media reactor designed to work with virtually any type of filter media. Its key strength lies in the innovative design that ensures an even and consistent flow of water from the bottom of the reactor to the top. This design maximizes the efficiency of the filtration media by ensuring that water contacts all media surfaces uniformly.

Adjustable Internal Plate for Media Separation
A standout feature of the Element M is the adjustable internal plate inside the reactor’s column. This plate allows you to divide the reactor into two sections, enabling the use of different media simultaneously within the same unit. This flexibility opens up several filtration strategies:
- Single Media Mode: Use one type of media or a blended media throughout the reactor for targeted filtration.
- Dual Media Mode: Utilize two different media by bisecting the column, allowing for multi-faceted filtration in one reactor.

Fluidization of Media for Enhanced Filtration
Another powerful feature of the Element M is its ability to fluidize media. By adjusting the pump and bypass valve, you can fine-tune the flow to keep certain resins in a fluidized state. Fluidization increases the media’s surface area exposure and contact time with water, improving its capacity to remove organics and nutrients.
Examples of media that benefit from fluidization include:
- AquaVitro Pure Phos – a phosphate-removing resin
- Seachem’s C-Cell Carbon Media – for organic removal
- AquaVitro Biogen – a biological media highly effective for reducing nitrates and phosphates when fluidized

This capability makes the Element M a highly adaptable reactor that can be tailored to a wide range of aquarium filtration needs, from freshwater tanks to complex reef systems.
Element Z Zeolite Reactor: Targeting Low Nutrient Environments
The Element Z reactor is specifically designed to harness the power of zeolite, a natural mineral known for its ability to absorb ammonia and other nitrogenous compounds. This reactor is ideal for reef systems where maintaining low nutrient levels is crucial for coral health and coloration.

Benefits of Zeolite Filtration in Reef Aquaria
By utilizing zeolite, the Element Z reactor helps create a low nutrient environment that reduces organic waste loads. This reduction has been shown to enhance coral coloration and overall aquarium aesthetics. Additionally, the reactor provides a habitat for beneficial bacteria that contribute to biological filtration.
Built-in Wash Feature for Optimal Performance
One unique aspect of the Element Z reactor is its built-in wash feature. We recommend using this feature one to two times daily to backwash the zeolite media. This daily rinsing helps reduce biofilm buildup on the zeolite, maintaining its absorption efficiency and ensuring it continues to support the aquarium inhabitants effectively.

Element Ca Calcium Reactor: Maintaining Essential Reef Chemistry
The Element Ca calcium reactor is essential for reef aquarists who need to maintain stable calcium, alkalinity, and magnesium levels. These parameters are critical for coral growth and the long-term success of reef tanks.
How the Calcium Reactor Works
The calcium reactor operates by injecting CO2 into a chamber filled with calcium carbonate media, such as Seachem Reef Reactor media. The CO2 acidifies the water inside the chamber, slowly dissolving the media and releasing calcium, carbonate, magnesium, and other trace elements into the aquarium water.
This process mimics natural ocean chemistry, providing a continuous and balanced supply of essential minerals to support coral skeleton formation and overall reef health.
CO2 Control and Safety Features
Proper CO2 management is crucial for effective and safe reactor operation. The Element Ca reactor integrates several features to aid this process:
- Use of a CO2 tank combined with a pH probe and CO2 controlling system for precise dosing.
- The pH probe placement allows rapid response by the controller to avoid overshooting CO2 injection, which saves CO2 and prevents harm to aquarium inhabitants.
- The CO2 recycling feature recirculates unused CO2 within the reactor chamber, maximizing efficiency and reducing costs.

Customizable Effluent Placement and Easy Maintenance
The reactor’s effluent tube can be positioned in one of three locations to suit your aquarium setup preferences. Additionally, the media chamber is designed for quick removal, making cleaning and media topping up straightforward and hassle-free.

Frequently Asked Questions (FAQ)
What types of media can I use in the AquaVitro Element M Media Reactor?
The Element M is compatible with virtually any type of filter media, including resins, carbon, phosphate removers, biological media, and more. Its design allows for single or dual media setups using the adjustable internal plate.
How does the fluidization feature improve filtration?
Fluidization keeps media particles suspended and moving, increasing surface area exposure to water and enhancing the removal of organics, nitrates, and phosphates. This is especially effective with resins like AquaVitro Pure Phos and biological media such as AquaVitro Biogen.
How often should I use the wash feature on the Element Z Zeolite Reactor?
It is recommended to use the built-in wash feature one to two times daily. This prevents biofilm buildup on zeolite, ensuring optimal nutrient absorption and maintaining a healthy environment for tank inhabitants.
Is a CO2 controlling system necessary for the Element Ca Calcium Reactor?
Yes, using a CO2 controlling system with a pH probe is highly recommended. It prevents CO2 overdose, maintains consistent dosing, and protects your aquarium inhabitants while maximizing the reactor’s efficiency.
Can I adjust the effluent flow location on the Element Ca reactor?
Yes, the effluent tube can be placed in one of three different positions to best fit your aquarium plumbing and preferences.
