Seachem Pristine 500 ml

Seachem Pristine uses natural bio-augmentation to rapidly and safely eliminate sludge and detritus, increasing water clarity in marine and freshwater tanks.

• Natural organic waste management.
• Rapidly and safely eliminates sludge and detritus.
• Helps increase water clarity.
• Marine and freshwater.

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 salt water and can utilize a wide range of organic compounds, including fats that can cause unsightly films. Unlike traditional nitrifying bacteria, this bacterial blend can adapt to harsh or low oxygen environments and continue to multiply and improve water conditions. Bio-polymers produced by established bacterial colonies trap particulates and increase water clarity.

Part of managing nitrate and phosphate levels — see our guide to Nitrate & Phosphate for why these two parameters are tracked together.

The Seachem Pristine 500 ml gives nitrifying bacteria a home to colonize as part of your tank's biological filtration — see our guide to the Nitrogen Cycle for how this fits into overall water quality.

Compatibility

Freshwater and marine. It is a live bacterial culture, so turn UV sterilisers and ozone off for two to three days after dosing.

Dosage & Directions

Use 5 mL for every 40 L (10 US gallons) on the first day, then 5 mL for every 80 L (20 US gallons) as required. Shake well before use.

Pristine digests sludge, uneaten food and excess organic waste. It works on the cause of a dirty tank rather than the symptom, so give it a fortnight before judging the result.

Freshness & Storage

Every batch we dispatch carries a minimum of 6 months' remaining shelf life. Store this product in a cool, dry place away from direct sunlight, with the cap or inner foil closed tightly after each use.
