"Release the Natural Beauty of your Planted Aquarium"

A beautifully planted aquarium creates a stunning focal point for any setting.  Live aquatic plants bring a living, breathing, exquisite part of nature into your home.  


  • It's easy... The CO2 Natural Plant System helps you achieve beautiful, thriving live aquatic plants, and ultimately, a healthier aquarium.

  • Visible results in just 15 days... when comparing plant systems using CO2 versus those that don't, the differences are very apparent. Most rapid growth plants obtaining CO2 injection, are more lush,colourful and grow faster
How it works

This system is designed to supply any aquarium with a safe, economical, and efficient method of providing nature's most powerful carbon source for plants. Employing a natural fermentation process for CO2 eliminates the need for inconvenient pressurized cylinders. It allows quick, easy, and affordable refills of ingredients to provide continuous CO2 for a 3-4 week period. The special fermentation canister was developed to support consistent carbon dioxide output.

Designed with Safety in mind

The fermentation process creates pressure, which in turn pushes the CO2 bubbles into the aquarium. A patented "Pressure - Release Safety Cover" was designed to prevent the internal pressure in the canister from exceeding safe levels.

The System:

  • All-natural Activator and Stabilizer ingredients are added to sugar and water in the Fermentation Canister.

  • Once sealed, fermentation commences. As CO2 forms, pressure builds, creating CO2 bubbles that travel through CO2 -resistant tubing into the aquarium.

  • There, the bubbles encounter the CO2 Bubble Counter/Diffuser, the key to efficient CO2 diffusion into the water. The CO2 bubble follows a patented 3-Dimensional, extended path. As it travels within the unique matrix, the bubble becomes smaller and smaller, finally disappearing almost entirely. This indicates that CO2 has fully dissipated into the water.
For Uniform Release of CO2

  • The Activator contains specially selected micro-organisms which trigger alcoholic fermentation of the sugar and create reliable production of CO2.

  • The Stabilizer slows down and prolongs reaction time, to support consistent performance.

  • Replacement Activator and Stabilizer packets guarantee the integrity and performance of the CO2 Natural Plant System
