Thetford has introduced Aqua-Kem Shotz, which the company says is the first micro-concentrated holding-tank deodorant in the RV industry. The 2-inch by 2-inch packet offers the same waste digestion and odor control as traditional Aqua-Kem Drop-ins. Shotz are formulated to liquefy waste and break down tissue fast to help prevent clogs, while the rapid-dissolving micro-concentrates deodorize the holding tank quickly, according to the company. Aqua-Kem Shotz are 100 percent biodegradable, and are available in an easy-to grip jar holding 24 doses.Â Available at Camping World. MSRP: $22.99.
