Camping potty savior - I am in a remote off grid cabin and have a little camping potty for overnight needs. I have been using it for over a year and never put chemicals or anything but soapy water in it to clean it. But now despite not ever going number 2 in it, it had gotten really stinky to the point that every time I opened the lid to use it, it would stink up the bathroom. I was skeptical but decided to toss one in (with a little water) after cleaning as usual. I am happy to say my potty doesn’t stink up the bathroom anymore. Smiley face! The pouch dissolved quickly and the ‘alpine’ scent is pleasant although not what I expected as a pine scent. But still even though it’s not the alpine I wanted, it still smells clean and fresh. Highly recommended.

I put one pod in a glass mason jar filled with water. The jar has measuring lines on side. I use 1/4 of jar at a time. According to directions, one pod for 40 gallons. My system makes 10 gallon servings. Still much for my 5 gallon tank, but better on wallet and environment. Very effective at this proportion. **Q: what is the scent? Is it over poewering or lightly scented?** A: A "fresh scent" without over powering. Great scent to accommodate with any holding tank **Q: Am i suppose to drop one in when it is full and right before I dump the waste or drop one in as the waste is building or when it's empty?** A: Dump a new packet into the tank, with a little water, immediately after you empty it. Then, the product will work to deoderize the waste water as it accumulates. **Q: Does this really help break down non-RV toilet paper? This is for my 5th wheel camper.** A: A few years ago (5-7?)I watched an informative youtube video made by a young RVer couple to perform a disintegration test of the expensive "RV Toilet Paper" versus a few top name brands and Walmart's "Great Value Ultra Strong 2 ply toilet paper" that states "safe for septic tanks". The Walmart brand disintegrated better than any other brand including the expensive "RV Toilet Paper" and for a LOT less money! 👍 I have been using the Walmart TP ever since with no problems. And I have used Walex Bio Pak in my 5th wheel black water tank since about 2015 or 2016 (and every 2-3 years use a load of Walex Commando but follow the directions VERY CAREFULLY). ## Customer Reviews ### ⭐⭐⭐⭐⭐ Yes!

These things smell amazing, I don't know how they did it. There is nothing worse than knowing something stinks, and the smell is trying to be covered by a more pleasant odor- this is not like that. These packets smell good and they don't have to try hard. They were bigger than I expected, one is supposed to treat 40 gallons. I figured we could add another one later in the season if needed as my tank is bigger than the 40 gallons. ## Frequently Bought Together - Walex Bio-Pak Black Holding Tank Deodorizer & Waste Digester Drop-Ins - Advanced Enzyme Formula for Rapid Breakdown of Waste & Paper, Removes Odors & Cleans Tank; Alpine Fresh, 10-Pack - Walex Porta-Pak Black Holding Tank Deodorizer & Portion Control System Drop-Ins - Rapid Breakdown of Waste & Paper, Odor Prevention, Cleans Tank & Sensors - Fresh Scent, 10-Pack - Thetford Porta Potti 365 Portable Toilet (for RV, Marine, Camping, Vans, Trucks, Healthcare) 92820, White --- ## 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.jp/products/1344455-walex-bio-pak-rv-black-tank-treatment-drop-ins-liquifies](https://www.desertcart.jp/products/1344455-walex-bio-pak-rv-black-tank-treatment-drop-ins-liquifies) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-08*
