F.O.G Klear uses natural bacterial tablets to help break down a build up of fats, oils & greases that have built up over time. Our tablets are completely natural meaning that no chemicals are used and its safe to handle. This is safe for all septic tanks, drain fields and drains. Septic Klear increases the time between expensive pump-outs on your septic tank which means substantial savings over the year. The natural enzymes in Septic Klear encapsulate the odour and seal it, while the bacteria digest the source of the odour. Septic Klear tablets are made up of bacteria and septic tank enzymes, with added nutrients, to stimulate bacterial activity and complement the indigenous bacteria in your septic tank.
