Seachem Pristine is a bio-augmentation supplement for freshwater and marine aquariums. It adds bacteria that break down excess food, waste and detritus, and it lowers ammonia, nitrite and nitrate that feed nuisance algae and disease organisms. It is a non-chemical alternative to manual cleaning and water changes, best for keepers with heavy feeding or messy stock. Compared with bottled nitrifying starters, it targets accumulated sludge and cloudiness rather than cycling a new tank.

Hobbyists who use Pristine report clearer water and less visible detritus in tanks with heavy bioload. Many treat it as a maintenance aid alongside regular water changes, not a fix for an overstocked or poorly filtered tank.
Seachem Pristine is a water quality product for freshwater and marine aquariums. It uses natural bio-augmentation, not chemicals, to add bacteria to the water.
These bacteria break down excess food, waste and detritus. They also reduce excess nutrients such as ammonia, nitrates and nitrites, which feed the growth of nuisance and disease-causing organisms.
Pristine increases water clarity and promotes better overall health in the aquarium. Seachem Laboratories designs its products with chemists and biologists.
