About Us

• Leveraging ten years of innovation at the Georgia Tech Research Institute, .ZeroFour provides the kinetic precision necessary to gradually and reliably drive phosphate concentrations down to desireable levels.
• Specialized media beads engineered to drive phosphate removal to a perfect equilibrium at the 0.04 ppm threshold, preventing the 'over-stripping' common with other products.
• .ZeroFour utilizes advanced selective binding to target phosphate ions without disrupting essential trace elements. This precision prevents algae outbreaks and stabilizes the environment, promoting superior coral health and pigment expression.
• Designed for effortless integration, .ZeroFour fits seamlessly into your maintenance routine without disrupting your tank’s delicate biological processes. Beyond phosphate control, its advanced formula assists in the removal of heavy metals and organic pollutants, ensuring a pristine environment for all aquatic life
• Protect your investment and your livestock with a solution backed by a decade of research. Choose .ZeroFour to enjoy a balanced, beautiful saltwater aquarium.

Using a patented formulation .ZeroFour provides natural even

A thriving saltwater aquarium is more than a display—it’s a carefully balanced ecosystem. Every parameter matters, and few are as influential as phosphate levels. When phosphates rise, algae takes over, water clarity suffers, and coral health declines.

ZeroFour was created to solve that problem precisely.

Developed from more than a decade of water-treatment research at the Georgia Tech Research Institute, ZeroFour is engineered to achieve equilibrium at 0.04 ppm phosphate—the level where reef systems perform at their best.

Using a selective binding process, ZeroFour targets and removes excess phosphates without disturbing beneficial biological processes. By addressing the root cause of algae growth, it restores balance where your aquarium needs it most.

With ZeroFour, you can expect:

• Reduced algae growth before it becomes a problem

• Clearer, cleaner water

• Healthier corals with more vibrant coloration

Fast-acting and easy to use, ZeroFour fits seamlessly into your regular maintenance routine, whether you’re managing a home reef or a professional system.

From hobbyists to experts, aquarists trust ZeroFour to protect their investment and keep their saltwater environments stable, healthy, and visually stunning.
