Review on Camco 41197 TST Ultra-Concentrate Orange Scent RV Toilet Treatment - Formaldehyde-Free Breakdown for Waste & Tissue - Septic Tank Safe - Treats 16-40 Gallon Holding Tanks (1 Gal) by Jodi Tisdale

We started using this liquid treatment when we realized that powder-filled bags in our black RV tank weren't enough. I researched the ingredients in both and found that when paired with powder treatment sachets, there were no harmful chemical interactions. It may have been an accident, but he seemed to be handling the smell better in this hot, hot summer. Follow the directions and add the recommended water to the tank if you add this - it won't work without water. I also use this in drains/grey tank versus gray tank processing. It makes no sense to keep both types in one motorhome.
