    My wife & I came across B.N.Solutions at 2018 Elmore field days. We have had constant trouble with our septic system since its installation 3 years ago. The sales woman at the field days gave us the big spiel in regards to SEPFIX & all it could & would do. We had tried a number of products with the same sort of sales pitch & thought well what have we got to loose. WELL. This product is everything it says it is & everything it says it does, Since using SEPFIX we have not had any odors at all, no more black water from the end of effluent lines & not had a blocked toilet. It is everything it says it is, Follow the instructions & you will not be disappointed. Jodie & I highly recommend this product, we will be returning customers for as long as we live with a septic system. Thanks much, Regards, Kim, Seymour.

    SepFix is a Game-Changer

    In our household, consisting of three bathrooms, we were confronted with an escalating and persistent foul odour emanating from our middle bathroom. Despite our best efforts, the situation seemed to be deteriorating rather than improving over time. It was evident that we needed a comprehensive solution to address this unpleasant issue.

    After conducting thorough research, I stumbled upon Bionatural Solutions, and I decided to reach out to Gary, seeking his expert advice regarding our problem. I inquired about Sepfix, and Gary promptly responded with insightful information about the root cause of the odour and how Sepfix could effectively resolve the problem.

    With Gary’s guidance, we decided to give Sepfix a try. After just one week of consistent application, we were astonished by the results – the foul odour that had plagued our middle bathroom for so long had completely vanished. It’s been a full month since we first used Sepfix, and the odorous problem has not resurfaced.

    We are beyond thrilled with the outcome and cannot express our gratitude enough to Gary and the Bionatural Solutions team for introducing us to Sepfix. If you find yourself grappling with odours originating from your sewerage or septic tanks, we wholeheartedly recommend Sepfix as a reliable and effective solution. It has not only eliminated our odour issue but has also restored a much-needed sense of freshness and comfort to our home. Sepfix by Bionatural Solutions has proven itself to be a game-changer in tackling stubborn bathroom odours, and we couldn’t be happier with the results.

    kind regards,
    Murray Kartal, Broadmeadows.
