Solutions for a Stinky Holding Tank
Additives prove effective in reducing tank odors, but ventilation is the key to keeping the stink at bay.
Practical Sailor testers looked at a large field of holding tank additives and found that chemical treatments that rely on disinfection, surfactants, and deodorants are better than nothing, but they still left that distinctive public-restroom smell. We also compared eight top-performing additives from a new generation of tank treatments that use enzymes and bacteria cultures to reduce odors. Tests showed that these bio-augmenting treatmentsincluding Odorlos, SeaLand Max Control, Camcos TST Citrus, Thetford Eco-Smart, Nature-Zyme, and Aqua-Kemreduced odors and reduced solids in the tanks, without the port-a-potty smell. We look at the pros and cons of these newer tank treatments, and examine the importance of tank ventilation in reducing odors.
