Muck Munchers XL is the UK's top-selling biological septic tank treatment, suitable for all types of tank (often referred to as cesspits), including modern package sewage treatment units. The Muck Munchers range of septic tank treatment bacteria products eliminate problems and reduce unnecessary pump-out costs so you can enjoy the benefits of maintaining a healthy septic tank, free-flowing blockage-free soakaways and drains. Muck Munchers XL is a flushable 12 x monthly probiotic septic tank treatment programme that reduces organic waste by up to 97%, saving you £100’s on unnecessary septic tank pump-outs. To guarantee success each 12-month Muck Munchers XL programme comes with a Free Kick-Start Bio-Booster starter Pack.Together they’ll maintain your system in tip-top condition, digesting organic material, including fats, oils and grease, while counteracting detergent, bleach and other chemical contaminants. By design, your septic tank naturally breaks down wastewater, cleaning chemicals and other pollutants. When this natural digestion process is disrupted the natural enzyme-producing bacteria in your tank are weakened and occasionally destroyed resulting in a build-up of fats, oils, greases, excessive sludge, foul smells and blockages. The monthly addition of Muck Munchers® septic tank treatment will maintain the ecosystem in your septic tank to promote the growth of the natural microorganisms (good bacteria) resulting in a reduction and the slowing down of build-ups, resulting in fewer pump-outs, odourless septic tanks and reducing the potential of soakaway problems.
