Brightwell Aquatics MicroBacter Clean - 250ml Brightwell Aquatics MicroBacter Clean - 250ml is a marine aquarium cleaning bioculture made with non-pathogenic microbes and natural enzymes. It helps clean live rock, decorations, aquarium surfaces, and substrate by loosening unwanted accumulations and supporting the breakdown of organic waste. Brightwell MicroBacter Clean for Marine Rock and Aquarium Surfaces MicroBacter Clean is especially useful during the post-cycle “ugly stage” and in marine aquariums where films, coatings, detritus, and nutrient-rich buildup make routine maintenance more difficult. It does not replace good husbandry, but it can make scraping, vacuuming, and surface cleaning easier over time. MicroBacter Clean 250ml Marine Aquarium Cleaning Benefits Provides natural cleaning action on aquarium and decoration surfaces. Loosens unwanted accumulations and coatings so they are easier to remove by scraping or vacuuming. Helps establish bacterial colonies that multiply and continue cleaning aquarium surfaces. Supports reduction of organic carbon, ammonia, nitrite, nitrate, and phosphate. Digests uneaten food, waste, detritus, and other organic material. Helps create cleaner substrate without requiring unnecessary disturbance of the substrate bed. Brightwell MicroBacter Clean Formula Notes and Normal Appearance Size: 250 ml bottle.
