Odor Eliminator: EcoStrong’s Toilet Drop-Ins keep away porta-potty smells three times longer by eliminating the sewer smell at its source and not covering it up with fragrances. It works in gray tanks too!
Faster Pump-Outs: The Pods contain 50% more biology that thoroughly liquefies human waste and breaks down toilet paper, making dumping easier and more effective.
Clean Sensors: EcoStrong Drop-ins combine a 100% biodegradable cleaner and anti-clumping agents with the highest potency bio-active formula to clean and restore black tank sensors and prevent clogs.
All Natural: RV Tank Pods do not contain formaldehyde, Zinc Sulfate, TSP (Trisodium Phosphate) or chemicals of any kind. They are safe for septic tanks, RV and boat holding tanks.
How to Use: Use only 1 pod per flush. If your tank is larger than 40 gallons, repeat steps 1, 2 & 3. 1) Fill the toilet with 1 to 2 gallons of water. 2) Drop one pod into the toilet and let dissolve. 3) Flush once dissolved and refill the toilet with a few inches of water.
