Seachem Pristine
Pristine uses bio-augmentation, a non-chemical and natural method, to improve water quality. It provides bacteria that break down excess food, waste and detritus in freshwater and marine systems. It will also reduce excess nutrients (e.g. ammonia, nitrates, and nitrites) that may fuel the growth of nuisance and disease-causing organisms. Pristine™ increases water clarity and promotes overall better health for the aquatic environment.
The bacteria species in Pristine thrive in fresh or saltwater and can utilize a wide range of organic compounds, including fats that can cause unsightly films.

FAQ
How does Pristine improve water quality?
Pristine introduces beneficial bacteria that naturally break down excess food, waste, and detritus in the water. These bacteria reduce levels of ammonia, nitrates, and nitrites, which helps improve water clarity and supports healthier aquatic life.
Can Pristine be used in both freshwater and saltwater tanks?
Yes, the bacteria in Pristine thrive in both freshwater and marine systems, making it suitable for a wide range of aquarium environments.
Does Pristine eliminate algae growth?
Pristine helps reduce the nutrients that fuel algae growth, but it does not directly eliminate algae. For effective algae control, additional measures may be needed.

I’ve used Pristine in my freshwater tank for three months now. The water has become noticeably clearer, and I see less algae buildup. My fish seem more active and healthier. No chemical smell or side effects. Easy to add to the tank.

It works well in my saltwater aquarium. After a few weeks, the water clarity improved and I noticed fewer fish with signs of stress. The bacteria seem to adapt quickly to the environment. I’d recommend it for both fresh and saltwater setups.

Great product for maintaining stable water conditions. I added it monthly during feeding cycles and saw a consistent reduction in nitrite levels. My shrimp and fish are thriving. No changes in water chemistry or pH.

Used it after a water change and noticed a difference in water clarity within a week. The tank didn’t smell off, and the fish didn’t show any signs of illness. Works best when used regularly, not as a one-time fix.
