Brightwell Aquatics MicroBacter7 is one of the world's most trusted aquarium bacteria. It is a complete bioculture of aerobic and anaerobic beneficial bacteria plus natural enzymes that builds and maintains powerful biological filtration in both reef and freshwater aquariums.
What it does
- Cycles new tanks – establishes biological filtration so ammonia and nitrite are processed quickly.
- Lowers nitrate & phosphate – helps reduce nutrients that fuel nuisance algae and cyano.
- Breaks down organic waste – enzymes digest detritus and sludge for cleaner substrate and clearer water.
- Trusted – tested and recommended by a veterinary pathologist; 2-year shelf life.
How to use
- New or high-nutrient tanks: 5 ml (1 capful) per 25 US gal (approx. 95 L) daily for the first 2 weeks.
- Established tanks: 5 ml per 50 US gal (approx. 190 L) once a week.
- Shake well. Turn off the protein skimmer and UV steriliser for 4 hours after dosing.
- Pairs well with Brightwell Reef BioFuel (carbon source) for faster nitrate and phosphate reduction.
