Review on 🔍 Discover the Power of Unique 413-1 RV Digest-It Holding Tank Treatment: 16 Treatments, 32oz (Packaging May Vary) by Boondo Viswanathan

I have used several drip and liquid products in two of our caravans. Many of them did not survive, or at best only eliminated the smell. Unfortunately I had a fallback to a lightly used caravan that we had bought. I've used most standard and tubing methods but nothing has managed to break the fuse. As instructed, I poured the entire 32 ounce bottle into our reservoir, filled it with water and let it sit for 24 hours. As soon as I opened the valve, the reservoir was completely empty. I was even more shocked to find that the gauges also showed a completely empty tank. i am sold Will be buying more and this will be my weekly storage tank maintenance going forward.
