Muck Munchers Xl 12 Month Programme Reduces Organic Waste by up to 97%

The ultimate non-toxic, natural biological septic tank cleaner ensures effective treatment, all-year-round –  plus  – a specially formulated bio-booster quickly activates your entire septic system and drainage-field outflow network.

Muck Munchers XL is a simple monthly, flushable soluble sachet treatment that can save you 100’s of £’s in expensive septic tank emptying and potentially 1,000’s of £’s on drainage system repairs and re-builds.

Plus – to guarantee success each 12 month Muck Munchers XL programme comes with a Free Muck Munchers Bio-Booster Start-up Pack.

Together they’ll maintain your system in tip-top condition, digesting organic material, including fats and grease, counteracting detergent, bleach and other chemical contaminants.

Just One Muck Munchers Programme is all Most Households Need

Muck Munchers are perfect for household up to 6 people. For large households if you have significant amounts of washing-up, laundry, baths and showers, you may need to double the dosage.

Shared Septic Tanks

If you share a septic tank with a neighbour, we recommend that you use separate packs for each property, if the total count exceeds six people.

Keeping Inlet Drains Clean

There’s great merit in applying Muck Munchers in different toilets each month. When you flush the sachet down the loo, a proportion of the microbes will attach to organic waste on the drain surfaces, increasing digestion and reducing the chances of blockages.

The best toilet to apply Muck Munchers initially is the one furthest away from the outlet drain to the septic tank.

Triple Action Bog Busters Tank Reactivator

If you have not had your tank emptied for some considerable time or you are experiencing slow drainage from the tank to the drainfield, it is advisable to first treat with Triple Action Bog Busters

This is an intensive treatment to reinvigorate stagnant septic tanks and very slow draining soakaways, using a powerful microbial treatment, together with an industrial bacterial grease digester and an oxygenator, which increases microbial activity 7 – 10 fold.  See more at Triple Action Bog Busters.

If you are also experiencing wet, boggy soil areas around your tank, do take a look at the next section, ‘Treating Boggy Soakaway Conditions’.

Treating Boggy Soil Soakaway Conditions

Soakaways can often become boggy in extremely wet in winter conditions or where there is a very high water-table. This will undoubtedly have been a long-term problem that can only be overcome by improving drainage from the area.

Most frequently, the problem is that not only have the outflow drains become far less effective, the surrounding soil particles have been coated with contaminants blocking the ability for free-drainage in to the surrounding area.

The recommended treatment programme is –

You will need to purchase Oxy-Tonic to use with some of your Muck Munchers XL sachets.

Secondary Tank

Dilute 200 – 250mls of Oxy-Tonic in 10 litres of water and pour in to the secondary tank.

Now, dissolve 2 sachets of Muck Munchers in 5 – 10 litres of water and again pour in to the secondary tank.

NOTE – if you are planning on using Triple Action Bog Busters you can omit this treatment and go straight to treating the Soil Area as described below.

Soil Area

Dilute 50 ml Oxy-Tonic in a 10 litre watering can and water over the boggy area.

Next, dissolve a Muck Munchers soluble sachet in the 10 litre watering can and water over the same area.

Now repeat the soil treatment again in the next day or two, and then with a single treatment weekly for the next 3 weeks.

How to Use

Muck Munchers + FREE Bio-Booster

Just Flush & Forget! 

1. Simply flush the soluble Kick-Start Bio-Booster down a toilet. It’s then best not to use the toilet for a few hours, to help ensure some microbes also populate drain walls to clean them up too.

2. Then each month flush down a Muck Munchers soluble sachet to maintain a healthy microbe population. If you purchase from our website we automatically send you a reminder on the 1st of each month.

TIP – If you have a slow-draining sink, dissolve a Muck Munchers XL sachet in luke-warm water last thing at night. Then let it flow into the trap and drain. Leave any residue until morning before flushing it away. It will digest fats, oils and greases coating waste pipes.

Great Product Great Value

So easy to use; so easy to store; works so well, there’s no point in looking for any other product. For a year’s supply, a very fair price.

Septic Tank Pump-Out Driver’s Comment

Our sceptic tank emptier is going to use Muck Munchers because he was so impressed – only 6-8” of sludge after 9 years for an 8 man tank.

Dosed only this morning. The tank has very little sediment in it and the little munchers are doing a great job.

Outflow Better… Drains Cleaner

Thank you for the Special Renewal Offer. After 12 months use of Muck Munchers, monthly email appreciated, I’m very impressed with the results. My septic tank outflow is a much higher quality than before and the drains cleaner.
