Thank you **Q: Can it be used in gray and black tanks the same way?** A: We really don't know about the use/purpose in the Gray tank, definitely in the black tank. Why not just something like Dawn dish detergent in the Gray tank? Just a thought, it's a good degreaser. **Q: This product uses 8oz single use bottles and another company has 4oz single use bottles. Which do you need?** A: My tank is 50+ gallons. I tried the 4oz version with poor results. Switched to the 8oz bottle and it works just fine. **Q: Is liquid blue** A: Cypress sent is green in color ## Frequently Bought Together - THETFORD AquaMAX Summer Cypress Scent RV Holding Tank Treatment, Formaldehyde Free, Waste Digester, Septic Tank Safe, 6 Pack 8oz Bottles (96689) - Thetford Aqua-Soft Toilet Tissue - Toilet Paper for RV and marine - 2-ply - Thetford 03300 (Pack of 4 rolls) , White - Camco Tastepure RV Water Filter - New & Advanced RV Inline Water Filter with Flexible Hose Protector - GAC & KDF Filtration - Made in USA - Camping Essentials for Fresh Drinking Water (40043) --- ## 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.tn/products/320952047-thetford-aquamax-summer-cypress-scent-rv-holding-tank-treatment-formaldehyde](https://www.desertcart.tn/products/320952047-thetford-aquamax-summer-cypress-scent-rv-holding-tank-treatment-formaldehyde) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-15*
