What is FOG?
As you may have guessed by now, we're not referring to tiny suspended particles of water. FOG stands for Fats, Oils & Greases which are the most common culprits for a clogged septic tank drain field.
How often do I use this?
Once a month. Simply use one tablet in your kitchen sink every month.
How long will it take to break down grease?
The bacteria will begin breaking down grease straight away. How long it will take depends on the amount of grease, think of the bacteria as ants and the grease as an elephant. If you have a London fatberg the size of an elephant, please be patient whilst the ants break it down.
