Valterra Pure Power Blue Waste Digester | 4 oz. Bottle, Treats 40-Gallon Tank

Valterra Pure Power Blue is a concentrated holding-tank treatment that breaks down waste and controls odor in both black and gray tanks. It's formaldehyde-free, so it won't harm the bacteria in septic systems or campground treatment facilities.

Just 2 oz. treats up to a 40-gallon tank, so this 4 oz. bottle covers a couple of treatments before you need a refill.

• Fresh, clean scent
• 2 oz. dose treats up to a 40-gallon tank
• Formaldehyde-free, non-toxic formula
• Safe for septic systems and accepted at campgrounds and dump stations

Add the dose directly into the tank through the toilet or a dedicated treatment port after each dump for ongoing odor control.
