I started using this product a few years ago when toilet paper was not breaking down in the septic holding tank. I’ve always been sceptical of adding any type of product to septic systems but trusted the professional that recommended it to me. Since using it there have been zero issues and improved breakdown of toilet paper in the holding tank. I did try the traditional “ baker’s yeast“ method for about a year prior to finding Septobac with no success. I would definitely recommend this product for overall septic health. Much more cost-effective than expensive septic repairs! The price tends to vary on 鶹 so I stock up when 鶹 lists it cheaper than my local store.
