Seachem Pristine

Seachem Pristine is a natural, non-chemical bio-augmentation that uses safe nitrifying and heterotrophic bacteria to break down excess food, fish waste, and detritus in freshwater and saltwater aquariums. The bacteria target the same nutrients (ammonia, nitrate, phosphate) that fuel nuisance algae and disease, so the result is clearer water and better long-term tank health.

Pair it with Seachem Prime for water changes, AmGuard for ammonia emergencies, and grab the matched SureStart starter pack if you are setting up a new tank.

FAQ

Does Pristine replace Seachem Stability?
No. Stability is for cycling and biofilter establishment. Pristine is for ongoing nutrient and waste management. Many tanks benefit from both: Stability during the cycle, Pristine weekly thereafter.

Is it safe with my medications?
Pause Pristine during antibiotic treatments such as KanaPlex or MetroPlex, since the antibiotics may kill the dosed bacteria. Resume once the treatment cycle is complete.

How long until I see results?
Most aquarists notice clearer water within a week and lower nuisance algae over 2 to 4 weeks of consistent dosing.
