Pristine 100ml (biological sludge remover)

Seachem Pristine is a bacterial preparation for aquarists who struggle with cloudy water, surface film, and a buildup of food residue and detritus in freshwater or marine tanks. It works through live bacteria that colonize the water and decompose organic material, so it suits hobbyists who want a biological rather than mechanical approach to water quality.

Why it matters

• The bacteria consume organic compounds, including fats, that otherwise form a proteinaceous film on the water surface.
• The bacterial colonies produce biopolymers that bind suspended waste particles, which improves water clarity.
• The blend is designed to stay active in low-oxygen or oxygen-depleted conditions, where many similar products lose effectiveness.
• Dosing is simple: shake the bottle, switch off UV and ozone, and add one cap (5 ml) per 40 l of water, followed by maintenance doses of 5 ml per 80 l.

What it works with

Pristine is intended for freshwater and marine aquariums of any size, provided the dose is scaled to the water volume. If the bottle is used alongside antibiotics, the medication should be removed with activated carbon and a water change should be carried out. UV or ozone should stay off for 2–3 days after dosing so the bacteria can establish. Recurring problems with high levels of certain compounds may point to overfeeding or insufficient filtration.
