Black tanks are holding tanks, not septic tanks. The material does not stay in long enough to be affected by beneficial bacteria.

I checked other websites and it appears there are differing opinions on this subject. Most usually concur that the waste doesn't stay in long enough for bacterial action to be useful. However that doesn't apply in my case as I live full time in my travel trailer. About once a month, sometimes twice, I will empty my black water tank. I generally empty the gray water weekly. Any problems with smell usually come from the gray water and generally it is shortly after I emptied the tank and didn't add any "Walex TOI-61776 Elemonate Grey Water Deodorizer and Cleaner". I add "Walex BIO-11530 Bio-Pak Natural Holding Tank Deodorizer and Waste Digester" to the black water tank. At the time I had added two of the Bio-Pak's to my black water with no change. I have not had this problem until I disinfected the fresh water tank. I also treated the gray water as well. The problem didn't go away until I emptied the black water tank. There was still a slight smell afterwards which according to the article I read was to be expected as it may take a couple of empties to get all the chlorine out. However at this time the bathroom is the best smelling room in the TT.
