This was the RV version ### ⭐⭐⭐⭐ Works extremely well *by H***H on June 10, 2024* Have tried numerous other black water tank additives and this one has worked the best!! It turns the entire solution into a uniform light brown & seems to breakdown all the toilet paper as no pieces are seen when draining tank. No issues with smells coming up out of black water tank when flushing. ## Frequently Bought Together - Eco Strong RV Toilet Treatment | RV Black Tank Treatment | RV Holding Tank Digestor, Odor Eliminator, and Cleaner | Perfect for Campers, RVs, Boats, 33 Treatments, Lavender - Camco Tastepure RV Water Filter - New & Advanced RV Inline Water Filter with Flexible Hose Protector - GAC & KDF Water Filter - Made in USA - Camping Essentials for Fresh Drinking Water (40043) - Camco TST Camper/RV Grey Water Odor Control - Removes Grease Buildup in Gray Water Tank, Sink & Shower Drains - 4oz Treats 40-Gal Holding Tank - Safe Septic Tank Treatment - Lemon, 64 oz (40256) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/322535152-rv-toilet-treatment-rv-black-tank-treatment-rv-holding-tank](https://www.desertcart.us/products/322535152-rv-toilet-treatment-rv-black-tank-treatment-rv-holding-tank) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-29*
