Pre-measured, water-soluble packets that break down waste and control odors in RV and marine holding tanks. Just toss one in and flush — no measuring or spilling. Fresh scent. 12-count box.
Aqua-Kem Toss-Ins bring the same trusted Aqua-Kem holding tank treatment formula to a pre-measured, no-mess format. Each water-soluble packet dissolves quickly once dropped in the toilet and flushed — no pouring, no measuring cups, no risk of spilling concentrated liquid on hands or surfaces.
The ultra-concentrated formula breaks down waste and toilet paper to prevent clogging, while delivering powerful odor control with a fresh scent. Each packet is dosed for one treatment, so there's no guesswork about how much to use — just toss one in after dumping the tank, or as part of regular maintenance between dumps. The 12-count box provides a dozen treatments.
• 12x Aqua-Kem Toss-In packets How to use: Drop one packet directly into the toilet bowl and flush with the usual amount of water. Use after each dump for ongoing odor control and waste breakdown.
Toss-Ins (96904 — this item): Best for convenience — pre-measured, no spills, easy to store and pack for trips. Great for occasional users or anyone who finds measuring liquid awkward. Liquid Aqua-Kem (96901, 8 oz bottles): Best for bulk value and flexible dosing — useful for larger tanks or frequent dumping where buying in bulk reduces cost per treatment. Both use the same core Aqua-Kem formula — the difference is purely format and convenience.
