OF® Microbac Series – Pro-Intro Cycle Formulation Capsules
The Leading Aquarium Beneficial Bacteria.

How OF® MicroBac helps you combat common but critical aquarium problems?
Why should I use MicroBac?
In an enclosed environment like our home aquarium and pond, fish stocking density is usually many times of what we find in the wild hence the aquarium biological filtration’s efficiency to break down organic waste is crucial to the success of your aquarium. It is therefore necessary to quickly establish a matured colony of beneficial bacteria that will help to break-down toxic ammonia, nitrite and nitrate; this process is also known as the Aquarium Nitrogen Cycle.
After years of continuous research and development in water treatment, Ocean Free has come up with MicroBac, a natural and organic formulation of beneficial bacteria, enzymes and micro-organism consisting of more than seven major bacteria species and strains (aerobic and anaerobic type) like yeast, nitrosomonas, nitrobacter, photosynthetic bacteria, and a special strain of beneficial bacteria. Our aim is to help hobbyists achieve sparkling, safe and quality water conditions for their fishes.
FEATURES
OF® MicroBac Series is a concentrated, encapsulated aquarium supplement designed to enhance beneficial bacteria growth and maintain optimal water conditions. Its encapsulation ensures a longer shelf life and reduces contamination risks compared to powders and liquids. Key features include establishing and maintaining the Nitrogen Cycle, breaking down organic waste, and reducing ammonia, nitrite, and nitrate levels. It prevents algae blooms by balancing nutrient levels and is highly recommended for giant/carnivorous fish tanks due to its effectiveness in waste management. OF® MicroBac Series also naturally enhances fish color pigmentation and is proven safe and reliable through lab and farm testing.

FEEDING GUIDE
IMPORTANT NOTES
- Do not use MicroBac with antibiotic or anti-bacteria products; only use 3-5 days after last application of antibiotic product.
- Due to active ingredients, the water will turn cloudy after application. The duration that the white cloud is visible depends on the level of contaminants. When higher levels of contaminants are present, this cloudiness lasts longer. Normal clearing time will take anything from 2 hours to 24 hours, but subsequently the water will become crystal clear!
- It is recommended to add a weekly dosage of MicroBac to maintain healthy colony of beneficial bacteria in order to ensure good water quality.
- Please keep MicroBac in cool and dry place.
- Aquarium used only, keep out of reach of children.
