Nobody wants to think about their black tank, and that's the point of these drop-in tablets — treat it once and move on with your trip. Each tablet is formulated to break down solid waste and toilet paper while controlling odor for up to seven days, and the formula is safe for septic systems.
Works for RV, marine, and portable toilet setups alike, so it's worth keeping a bag on hand whether you're parked at a campground or anchored offshore.
