Sulfur denitrification was originally developed for the treatment of waste water in water treatment plants. This extremely effective process was translated for use in numerous public aquariums with great results. Once the potential of sulfur denitrification in marine and reef aquarium was realized, more and more hobbyists have been taking advantage of this nitrate-reduction technology.

There are several advantage of Sulfur Denitrification:

  • Simple to set-up and manage
  • Needs no additional feeding with carbon based foods or to monitor feeding
  • Works well without the cost of additional electronic control
  • Does not require a protein skimmer to work
  • Will supply additional calcium to the tank when used as per instructions.
  • Units can be used in series for management of higher nitrate levels.
  • Long lasting: media lasts up to 2-3 years
  • Units can be easily refilled or serviced
  • Can be used for freshwater or saltwater

Computer-Precision Engineered
AquaMaxx TS-3 Sulfur Denitrators are computer-precision engineered and utilize the latest aquarium technology to deliver unparalleled performance and value. Despite its small form factor and compact footprint, the TS-3 is rated for aquariums up to 800 gallons.

An effective and convenient inlet filter helps to trap particulates, extends the life of the pump and makes tuning the effluent drip rate as easy as possible. The high-quality pinch value allows for precise effluent control. Simplified inlet and outlet designs also improve efficiency. The unique pump baffle enclosure helps to minimize noise.

AquaMaxx Sulfur Denitrators are designed from the ground up with the aquarium hobbyist in mind. The computer precision-cut enclosure makes the reactor look and feel seamless.

Cleaning and maintenance is simple. Thumbscrews and keyhole flanges allows for easy removal of the lid.

The workhorse powering the AquaMaxx TS-3 Sulfur Denitrator is the pump. Each reactor is equipped with an Italian-made Sicce Syncra 2.0 pump. These pumps were chosen specifically for their small size, energy-efficient design and whisper-quiet operation.

Product Questions

The item description says a Synchra 2.0 pump is included with this. However, there's an "*" at the bottom that says Feeding pump and media are required and extra. The media I get, but, I'm confused, does this require two pumps, is the description wrong or is the * note wrong?

Thank you for clarifying!

The Sicce pump that is included is strictly for re-circulation within the reactor. The feed pump is required to deliver the tank water to the reactor. Sulfur can be purchased on amazon by searching "soil sulfur pellets"
