RAPID NITROGEN CYCLE ESTABLISHMENT: Packed with billions of live, active nitrifying bacterial cultures (including Nitrosomonas and Nitrobacter strains) that rapidly seed filter media. Speeds up biological maturation in new setups, preventing "new pond syndrome" and establishing an active, self-sustaining biological ecosystem within days rather than weeks. AMMONIA & NITRITE NEUTRALISATION: Actively breaks down lethal dissolved ammonia and toxic nitrites generated by fish excretion, uneaten food, and decaying organic debris. Prevents dangerous toxin spikes during heavy feeding seasons, stocking additions, or seasonal bio-filter lag, protecting fish gills and vital organs. BIOLOGICAL MEDIA ACTIVATOR & SLUDGE REDUCTION: Colonises all types of mechanical and biological filter media—including ceramic rings, bio-balls, K1 media, Japanese matting, and filter foams. Natural heterotrophic enzymes digest trapped organic mulm and bottom sludge, preventing media clogging and extending intervals between filter cleanings. ESSENTIAL FOR SPRING RESETS & FILTER MAINTENANCE: Cold winter temperatures naturally deplete beneficial bacteria colonies. Applying this liquid booster kickstarts biological filtration in early spring as water warms above 10°C, and rapidly restores lost bacteria populations following medication courses, routine foam rinses, or heavy water changes. WILDLIFE-SAFE & EASY APPLICATION: Completely free from harsh chemicals, synthetic stabilisers, and artificial dyes. 100% safe for sensitive fish (including Sturgeon, Sterlets, and Golden Orfe), pond plants, frogs, newts, and garden wildlife. Pour directly into biological filter chambers or near water return flows for optimal microbial dispersal.
