Thetford AquaMax Holding-Tank Treatment | Summer Cypress Scent, 64 oz

Thetford's AquaMax holding-tank treatment uses a triple-enzyme formula to break down waste and tissue in your black tank, helping prevent the clumping and clogging that lead to stuck valves and lingering odor.

It's formaldehyde and bronopol free and meets California's compliance standards for holding-tank treatments, so it's safe to use at campgrounds with tighter chemical restrictions. Thetford designed it to be safe for RV and marine toilets, holding tanks, and septic systems alike.
