Septic tank activator for (re) activation of the septic tank.

Do you want to reactivate your septic tank after a longer standstill or complete emptying and put it back into operation again?

Then the septic tank activator is the right package for you. The Septic Tank Activator consists of 2 bottles Roebic Septic Tank K37 and is suitable for a septic tank with a capacity of up to 1000 gallon.  Do you have a larger septic tank? Then you can of course order an additional K37 bottle directly.

Function of the Septic Tank Activator

Septic tank activator contains a large population of septic tank bacteria that (re)activate the decomposition of sludge and waste products in the septic tank. By adding the Septic Tank Activator, additional bacteria are added. Bacteria that can help the micro-organisms present in the septic tank to break down waste products. The accumulation of sludge and other deposits is then slower and less stench is released. This prevents many problems and activates and supports the septic tank in the right way.

Content of the Septic Tank Activator package

The septic tank activator consists of 2 bottles of Roebic Septic Tank K37.

Roebic Septic Tank K37 can be used for all types of pipes and lines. And because it is 100% biodegradable, Roebic Septic Tank K37 is not harmful to the environment. The Roebic Septic Tank K37 can be used for systems that are connected to both grey water (kitchen, bathroom) and black water (toilet). If the septic tank is only connected to a toilet, i.e. only to black water, we recommend Roebic Cesspool k47.

Do you have a septic tank with ventilation? Then it is better to use Roetech 106 PS. These are other bacteria cultures.
