Valterra Odorlos V77004 Holding Tank Treatment

When added to holding tanks, Valterra Odorlos Holding Tank Treatment provides the naturally occurring bacteria with a continuous supply of the best alternative energy source to pure oxygennitrates. This eliminates the need for bacteria to target sulfate for energy, and the result is no holding tank odors. It is safe and effective for RV and marine holding tanks as well as septic tank systems. This economy sized bottle can be used to refill Odorlos self-measuring bottles or pour directly into your toilet to flush into your holding tank. For black or gray water holding tank systems, use 4-ounces of Odorlos plus 1-gallon of water to treat a 40-gallon tank. It is recommended to flush and empty the system weekly for optimal performance. To prevent odors/backup in a septic tank, use 16-ounces of Odorlos plus 4-gallons of water to treat a 1000-gallon tank. For portable toilets, use 2-ounces of Odorlos plus 1 to 2 quarts of water. Do not mix Odorlos with other holding tank products.
