Septic Tank Complete Care Kit: Shock Treatment + 12 Month Aftercare




Our Complete Care Kit combines the UK's leading shock treatment for septic tanks with a complimentary twelve-month aftercare program, providing a comprehensive solution to establishing and maintaining healthy conditions within new, recently emptied or failing systems. Shock treatment combines two mutually beneficial products - dried bacteria and liquid septic tank nutrient - and is applied over the course of one week to provide a huge boost to your tank's overall microbe levels. These two synergistic treatments are then applied again every month to keep the system topped up. Tanks treated using the Complete Care Kit are less likely to encounter expensive blockages or unpleasant smells - and will last much longer between routine pump-outs.

This works well! "It arrived the next day. It was easy to use, it took about a week to work, which is what we expected, and the smells have all disappeared." - Julie SherlockRead review

Very pleased so far! "So far, so good. The smell used to be quite hard to take at times, when the wind was blowing in the wrong direction. Have been using the product for a few months now and no horrible smells." - Lydia M Read review

Septic tanks are dynamic microbial communities and are sensitive to certain substances and types of behavior. Check out our User Guide to find out what to avoid.
