Stimulates Bacterial Activity – Reduces Odours Fast  – Accelerates Bacterial Waste Digestion up to 10 Times Faster

Muck Munchers Oxy-Tonic Bio Accelerator quite simply helps friendly bacteria to break-down and digest waste and do their job more efficiently.

This oxygen rich stimulant turns poorly active anaerobic septic tanks into highly active aerobic environments – where bacteria can consume seven to ten times more waste.

In addition to increasing bacterial digestion levels, Oxy-Tonic is specially formulated to migrate quickly into the biomass in your septic tank, to speed-up the initial activation time. It is harmless to the environment, will not damage treatment plants, waterways, and, is beneficial to soil improvement and plant growth.

Oxy-Tonic is a highly effective septic tank deodoriser – eliminating foul smelling sulphur gases and methane.


While treating your tank with Muck Munchers should start to clear up ‘black-slimy’ anaerobic bacteria and grease in the drainfield, if you also have very boggy soil around the tank, it should be treated too.

The problem that you are experiencing 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

Using 300ml Oxy-Tonic and Muck Munchers XL

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

Oxy-Tonic is effective in eliminating smells on damp walls and floors. It helps rid those musty smells that frequently occur in poorly ventilated areas and damp walls following flood damage.

Dilute 100ml in 1 litre and spray or wipe over effective area.

How to Use

Initial Treatment

1. Pour 250ml (¼ of the litre bottle) of Oxy-Tonic down a toilet or sink, followed by approx. 10 litres of water. This will start to aerate your septic system.

2. The product will start to migrate through the biomass in your system and you should notice a marked improvement in odour within a few days.

3. To maintain a healthy septic system use a monthly Muck Munchers XL treatment programme. This will optimise digestion of sewage, toilet paper, and, fats, oils and greases all-year-round.

Repeat Treatments – Where there is a continuing problem with smelly tanks or drains, flush down a 100ml of Oxy-Tonic weekly, until odours disappear.

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.

Digesta Digests It

Really rate this product. Stuck some down in the showers and the water flows down the plug hole really well now. Also great at removing grease from the kitchen sinks.

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.

Used My Monthly Treatment Today

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.
