Gray an black tanks always stink but the plumbing is designed so you don’t smell them during normal use. If you can smell your tanks you have a vent and/or trap problem you might address. I’m on my third MH and stopped using chemicals 20 years ago after I realized I didn’t need them.

My apologies to the virgins.
