A complete biofilm removal system for use with the Alpron system. The kit is designed to complete a second biofilm removal protocol if needed. The clear hypochlorite concentrate solution is used to open up the water channels in the biofilm, and the biofilm is then removed with flushing using the mixed solution of citric acid crystals and activator. During this process (pH shock) the dissolved, stubborn residues are totally removed and are visibly rinsed out without causing any blockages to equipment. Kit includes Citric Acid Crystals 160g, Activator 20ml and Dip Slide.
