Unit price perIf you're dealing with the build-up of fats, oils, and grease (FOG) in your septic tank or drain field, FOG Klear is the solution you need. Over time, kitchen waste can cause FOG to accumulate in septic tanks and drain fields, leading to blockages and potential backups through the soil.
FOG Klear is a specially formulated septic tank treatment containing a blend of powerful bacteria that break down FOG in your kitchen drains, septic tanks, and drain fields. By using FOG Klear regularly, you'll help your septic system run more efficiently, reduce the risk of clogs, and avoid the unpleasant task of manually cleaning grease.
Not only will it help prevent future build-ups of FOG, but it also works to eliminate unpleasant odours caused by accumulated waste. Each pack contains 12 tablets, offering a simple and eco-friendly solution to maintaining your septic system, all while coming in a sustainable packet.
Keep your septic tank running smoothly and odour-free with FOG Klear—the easy, natural way to tackle fat, oil, and grease build-up.

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.
Once a month. Simply use one tablet in your kitchen sink every month.
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.

"I think it will need two or three applications to clear properly"
"It does seem to have done anything. Used 1 tablet in sink as instructed plus two tablets direct to liquids tank. Also used the Septic Klear product (1 via toilet and 2 in the solids tank). I wasn't expecting it to do much as I suspect the ground around our ancient brick tank is clogged with FOG, along with saturated soil from the wet weather. I'd hoped to see some improvement but the liquid tank is still not dispersing quickly enough, so waste of money."
"Put to use as soon as Igot it time will tell."
"Based on the septic tank product I expect it to work well but have not used it yet"
"We have used this over past year and it works well, so made another purchase"
