This concentrated biological treatment adds naturally occurring bacteria that metabolize nitrates rather than sulphate, preventing odour generation in RV holding tanks. The unscented formula promotes tissue and waste disintegration to minimize blockages. As a non-toxic, formaldehyde-free concentrate, installation requires no protective equipment or respirators.
