Is Ecover suitable for my septic tank?
Yes. Look for the “safe for septic tank” logo on your favorite Ecover product to check for septic tank safety. If you have a septic tank then you should be using products that can fully degrade. In your tank, there is an anaerobic environment that efficiently decomposes waste, and to keep it healthy you need to make sure you don’t upset it with unwanted chemicals that might throw it out of balance.
