Do you want to prevent odours and blockages in your septic tank? Then Roebic K37 is the product you need. Roebic Septic Tank K37 is a biological product that consists of a special mix of patented bacteria cultures. These bacterial cultures accelerate the decomposition of toilet waste in the septic tank. Stench, blockages and no toilet flushing are prevented. Roebic Septic Tank K37 is safe for all different kinds of pipes. And because it is 100% biodegradable, Roebic Septic Tank K37 is not harmful for the environment.
New! Even more concentrated and 40% less plastic
This product is now even more concentrated! A 250 ml bottle is suitable for a septic tank of no less than 1,500 litres. So you do not compromise on the efficacy of the product, but you do save on the use of plastic. A bottle contains 40% less plastic. Good for your septic tank and for the environment.
Roebic Septic Tank K37 can be used for systems that are connected to both grey (kitchen, bathroom) and black (toilet) wastewater. When the septic tank is only connected to a toilet, i.e. only to black water, we recommend Roebic Septic Tank K47.
Note: An important point with a septic tank, or this type of product, is that the use of chlorine is out of the question. Chlorine and other disinfectants will cause the biology in the septic tank to die. Fortunately, there are plenty of alternatives. You can read more about them on this page.
1 Bottle of 250ml Roebic Septic Tank K37 is enough for a septic tank with a volume of up to 1,500 litres. The best results are achieved by dosing once a year, for example after the system has been cleaned.
No, Roebic K37 is not suitable for this purpose. For an aerated septic tank, it is better to use Roetech 106 PS. These are different bacteria cultures.
It is best to add Roebic K37 a few days after emptying or starting up the septic tank and then repeat this annually as a maintenance product.
Roebic K37 can indeed help to reduce the amount of sludge. It does this quite quickly, however in the long run emptying will occasionally be necessary because the bacteria only break down organic material.
Yes, it is. Roebic K37 is a preventive product.
In case of a septic tank or WTP, be careful with cleaning products that contain chlorine! These can seriously disrupt the biology in the tank.
Problems with the pipework leading to the septic tank can be tackled with Roebic K97.

To protect the products from damage, we use – if necessary – packing paper as filling material in our packages. The packing paper is made of 100% recycled paper.
Will you help us recycle? You can recycle the packaging with the old paper and plastic waste so that it can be reused.
In our webshop we sell several organic and ecological cleaning products, which are suitable in combination with a septic tank, cesspool or domestic wastewater system without affecting the function of the bacteria.
We also take packaging and shipping into account. We use bio-based adhesive tape and compensate our CO2 emissions.
