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 species of bacteria in Pristine are a unique blend, specifically developed for hardiness and their ability to adapt to a wide variety of environmental conditions.
The bacteria species in Pristine thrive in fresh or salt water and can utilize a wide range of organic compounds, including fats that can cause unsightly films. Unlike chemical treatments, Pristine works naturally to maintain a balanced ecosystem.
| Key Benefits | Application |
|---|---|
| Breaks down food waste and detritus | Use weekly in freshwater or marine tanks |
| Reduces ammonia, nitrates, and nitrites | Recommended for new tanks or during water changes |
| Improves water clarity | Best used in conjunction with regular maintenance |
FAQ
How often should I add Seachem Pristine to my aquarium?
Add Pristine once every week for freshwater tanks or every two weeks for marine systems, depending on tank size and bioload.
Can Pristine be used in both freshwater and saltwater systems?
Yes, the bacteria in Pristine are effective in both freshwater and marine environments.
Does Pristine work immediately after adding it to the tank?
The bacteria begin to establish within a few days, but full effectiveness may take up to two weeks. Regular water changes and tank maintenance support faster results.

I’ve used Pristine for three months in my 55-gallon freshwater tank. The water clarity has improved noticeably, and I see fewer algae blooms. The fish seem more active and healthier. No strong smell or residue after use.

It works well in a mixed community tank with fish and shrimp. I added it once a week after feeding. The water looks cleaner and the ammonia levels dropped after a few weeks. Slight improvement in fish behavior.
Dylan Anderson –
After switching from chemical water conditioners, I noticed a significant reduction in nitrite spikes. The tank feels more balanced. I use it every two weeks in my marine setup and it’s been stable for months.
