BIOACTIVE DESCALER is an environmentally, sustainable, highly effective cleaning, descaling and maintenance mixture, in tablet form, for toilets, drain lines and sewage tanks. It offers odor elimination at its source and maintains pipes and tanks clean. BIOACTIVE DESCALER is backed by years of research by the experts at Marichem Marigases laboratories who developed its innovative dual-layer treatment process. Its blue effervescent layer dissolves first, using the natural power of citric acid to remove lime and mineral (scale) build-up. The second layer is then activated, whilst employs ultra-effective microorganisms to stabilize pH values and eliminate odor. These specifically selected microorganisms attack odor-producing organic matter, eliminate urine scale, prevent clogs and encourage the growth of active flora.
