How to Set Mega Munchers to Work

1. Flush the 1 litre container of Oxy-Tonic down a toilet or pour direct into the inward tank chamber. For optimum effect, apply when there are minimum discharges to the tank for for a few hours.

2. Next, take 3 of the Mega Munchers Soluble Sachets and flush down a toilet, one by one, or drop directly in to the inward tank chamber.

3. It’s best to not flush again for a few hours, as some of the microbes will then start to attach themselves to organic material in the drainage pipes and help digest that too - leaving you with cleaner inward drains.

4. Refer to the chart below for the frequency of further treatments which you simply flush down a toilet as described in point 3.

TIP – If you have a slow-draining sink, you can dissolve the Solu-Pack in luke-warm water last thing at night. Leave it in the sink for 10-15 minutes and then let it flow into the trap and drain. Leave any residue in the sink until morning before flusing it away. It will then help clean foreign organic material from the drain as well as your septic tank.
