💎 Black Diamond’s “GET SERIOUS” R.V. Boat Toilet Treatment is a blend of billions, yes billions of Bio-renewable multi-strain cultures that will continually produce enzymes that break down and digest fats, greases, toilet papers, carbohydrates, proteins, and other food waste keeping your system smelling fresh and running smoothly reducing the risk of solids forming. Our concentrated blend of cultures and surfactants aggressively destroys odors rather than dye-free masking them. Our formula stays active and offers excellent residual benefits in between pump-outs thus prolonging the need to pump out as often. No harmful formaldehyde, non-staining dye-free, septic tank safe, treats black and grey water tanks.
