A living enzyme that you add to your toilet waste tank to break down solids and reduce odour without the bulk of a water based product. Flush one teaspoon of Silky RX per month (or as required) into the toilet bowl to control odour, liquefy waste and reduce solids in holding tanks or cassettes. In temperatures below 15C a double starter dose may be required to initiate Silky RXs unique Enzyme formula. Remember to store Silky RX below 45C to preserve optimal biological action and avoid enzyme neutralisation. Avoid using a flush containing any biocides as this will kill the enzymes.
