Home About Us Feedback Add Us Description Seachem Pristine improves the water quality of freshwater and marine aquariums using bio-augmentation, a chemical-free, natural process that safely eliminates waste, sludge, excess food, and detritus. It also reduces ammonia, nitrates, and nitrites, while enhancing water clarity and overall health. * Natural organic waste management treatment * Rapidly and safely eliminates sludge and detritus * Safe for freshwater and marine aquariums Bio-augmentation uses beneficial bacteria cultures to break down and remove potentially harmful compounds in your aquarium water. By removing excess nutrients, it reduces the risk of nuisance and disease-causing organisms and helps keep the tank clear and safe. Unlike traditional nitrifying bacteria, the bacteria used in Pristine can adapt, multiply and remain effective even in harsh or low-oxygen environments. While the bacteria consume harmful compounds, they create biopolymers that help trap particulates to increase water clarity. Directions: Shake well before use. Turn off UV/ozone. Use 1 capful (5 mL) for each 40 L (10 US gallons). Then use a maintenance dose of 1 capful (5 mL) per 80 L (20 US gallons) with additions of livestock or the disruption of the biofilter through cleaning or medications. Antibiotics should be removed with fresh carbon and a water change before adding bacteria. Allow 2 or 3 days for the bacteria to become established before using UV sterilizers or ozone. Recurring problems with high nutrients can indicate overstocking, overfeeding or inadequate filtration.
