Review on 🚽 TankTechsRx - RV Holding Tank Treatment & Cleaner - 33.8 oz | 68 Treatments - All Natural Probiotics for RVs, Marine, Camping, Portable Toilets by Carlos Reyes

Excellent product; bought 2 bottles and went through the first to clean the tanks and gauges and traveled around for 6 weeks. I could have saved some of that first bottle if I had read the instructions a little better. After the tanks are completely empty, if full add 2 oz. of treatment we could smell the reservoirs after some use the first day so I added another 2 ounces and all seems fine. Well, if you're doing it right, start with 2 ounces. and a few liters of water. When you're full, throw some away and leave some in the tanks. I now have SeaLevel gauges and can see when the tank is 4% full and then add 1 ounce. Treatment, carry on and NO smell. If you have gauges that tell you it's 1/3, 2/3 or full, visit their website and you can learn how to tell when there's about 1 inch left in the tank. It's really important.
