Absolute Bio-Gel is a highly effective biological filter booster, packed with millions of live, natural nitrifying bacteria specially developed to support the startup and ongoing health of biological filtration systems. Ideal for new ponds, upgraded filters, or post-maintenance recovery, Bio-Gel helps establish strong, stable nitrification — fast.
Unlike standard liquid treatments, this advanced gel-based formula clings to filter media, allowing bacteria to colonise more efficiently and start working immediately. It rapidly kickstarts the nitrogen cycle, helping eliminate ammonia and nitrite while building a healthy, balanced ecosystem.
