Which activator for your septic tank?

Four, six or twelve months, sachets or micro-beads: on the shelf, it all looks the same. Two questions are enough to choose.

All the activators contain the same formula. What changes from one box to the next is the quantity and the rhythm. Answer two questions, and the shelf becomes simple.

How many people live in your home?

The dose goes in once a week, at bedtime, into the toilet. It depends on the number of people:

  • 1 to 4 people: 1 dose per week.
  • 5 to 8 people: 2 doses per week.
  • More than 8 people: 3 doses per week.

What the durations on the box mean

They apply to a household of up to four people. A family of six uses it twice as fast: a twelve-month box lasts them six months.

  • 4 months: 18 sachets.
  • 5 months: 22 sachets, the 4-month format with one month free.
  • 6 months: a 750 g tub with its measuring scoop.
  • 12 months: 54 sachets, or a 1500 g tub.

Do you want to think about it every week?

If the answer is no, choose the micro-beads. A single application releases bacteria for months. It is the format for holiday homes and rentals.

  • Micro-beads 6 months: pour a 500 g box into the toilet bowl, flush twice, done.
  • Micro-beads 12 months: two 200 g sachets, one now, one six months later. One sachet treats a tank volume of 1 to 3 m³.

Three situations, three answers

1

Family of four

A 6 or 12 month tub, one dose on Sunday evening. The simplest and cheapest option.

2

Holiday home

The 12-month micro-beads. Nobody is there for the weekly dose.

3

Six people or more

Two doses per week. Choose the 12-month format: it will last six.

And if the tank is already in trouble

An activator maintains, it does not repair. Slow drainage, odours, a tank just emptied: start with the Septic tank unblocker or the Septic tank emergency treatment, then resume maintenance one week later.

The doses for our products are on their packaging, and that is what counts. If swallowed or splashed, call the Poison Centre on +32 70 245 245 and keep the packaging to hand.
