High Efficiency Nutrient Control
BACTO REEF BALLS contain highly effective bacteria cultures that control nutrient levels ​​and help avoid unsightly algae growth in saltwater aquariums. Such results are achieved through the use of our timed-release carrier material.

Special Composition
The unique composition of our carrier material has been specially developed for use in seawater. It allows for a steady supply of diverse bacteria cultures to be added to the aquarium. Other materials such as normal gel acts as an additional carbon source and thus dissolves faster and makes controlled delivery impossible.

Ingeniously Simplified Dosing
Bacto Reef Balls are super easy to use. Simply place the necessary amount of Reef Balls into your filter and replace every 2 weeks when the original sphere is dissolved. Our seawater stable polymer matrix allows bacteria to be slowly added into the aquarium. A steady supply of beneficial bacteria removes the need for daily dosing and unwanted Dosage peaks.

Natural and Reef Safe
Bacto Balls is the first bacteria-based product to feature time-release technology in a sphere. Both bacteria and carrier material are 100% reef safe and promote a healthy and natural aquarium. As soon as the bacteria is introduced into the aquarium, the bacteria begins its task and reduces nitrogens and phosphates. Our blend of bacteria has been specially developed to suit the needs of reef aquariums by providing a stable and diverse bacterial culture. Any excess bacteria becomes a food source for corals and protozoa and are skimmed by a protein skimmer.



  • Make sure the spheres are not placed near the suction of a pump
  • BACTO BALLS slowly dissolve upon contact with water slowly for the next 2-4 weeks. During this time, natural bacteria, as well as a highly effective enzyme solution is introduced into the water.
  • After adding BACTO BALLS, your skimmer performance may significantly increase. This is the first sign of an increased nutritional degradation. With increase or removal of BACTO BALLS, you can determine the exact needs of your aquarium.
  • A general dosage can not be specified due to the individuality of aquariums and their stocking levels.
  • We recommend that you start with half the recommended dose and gradually add more BACTO REEF BALLS until you achieve your desired values. Check with regular water tests.
