Continuum BacterGen•M is a marine-specific live bacterial culture for cycling new saltwater tanks and supporting biological filtration in established reef and fish-only systems. This listing highlights the 250 ml bottle. It supplies aerobic and anaerobic microbes aimed at nitrification and denitrification, and at breaking down leftover food, detritus and organic sludge in seawater—where many freshwater-oriented bacteria products struggle. Shake well. Mix the dose into a cup of tank water, stand a few minutes, then add near live rock or bio-media—not straight into a pump intake. New tanks: about 5 ml per 100 L daily for two weeks or until the cycle settles. Medium to heavy bioload: 5 ml per 100 L daily as needed. Low-nutrient reefs: 5 ml per 200 L once or twice a week. Continuum often pairs it with Reef Micro•Fuel as a carbon source for the bacteria. Useful for reef keepers starting a new marine system or refreshing bacterial populations after big cleans or medication. The 250 ml pack suits nano to mid-size tanks and spare dosing without committing to the larger bottle. Brand: Continuum Aquatics Size: 250 ml New tank dose: ~5 ml per 100 L daily (first ~2 weeks) Established / low nutrient: scale down per label guidance above
