We’ve been on septic in a two story house and have used 10x Concentrate for years. We found this product to be extremely useful to optimise the septic tank; stopping drain smells creeping up from showers, basins, toilets; and for household cleaning.
Our house has find this product to be very powerful requiring only a small amount to be used with water when mopping tile or lino floors, cleaning the cookstove, cleaning greasy applicances, or even deodourising the eski after fishing.
10X Concentrate is a good alternative to acid or caustic cleaners which tend to kill the tank. It also has a fairly pleasant vinegary rummy smell. We typically go through 4L every 4-6 months but we use it for more than just the tank – its great value product.
