Star brite RV Bio Odor Enzyme Holding Tank Treatment - 32 oz

Control holding-tank odor by supporting waste and toilet-paper breakdown rather than simply covering the smell. Star brite RV Bio Odor uses a bioactivated enzyme formula intended for RV, marine, and compatible septic holding tanks, making it useful for routine black-tank care during travel and storage preparation.

What it does

• Helps digest waste and toilet paper when used as directed.
• Targets holding-tank odors without relying on a perfume-only approach.
• Continues working after the initial treatment as the bioactivated formula remains active.
• Suitable for RV and marine holding tanks and compatible septic systems.

Dosage and activation

1. For best results, flush residual chemicals and treated effluent from the holding tank with fresh water.
2. Use 1 fl. oz. of treatment per 5 gallons of tank capacity.
3. Shake the container well.
4. Add 32 fl. oz. of warm water to the toilet bowl, add the measured treatment, and allow it to activate for 30 minutes.
5. Flush the mixture into the holding tank.
