By Patrick Smith · Updated July 10, 2026 · How we review
Tank treatment is the one RV consumable where skipping a dose has immediate social consequences, and Camco's TST MAX drop-ins are built around removing excuses: no measuring, no blue liquid to spill, one pod per dump-and-refill. Full-time RVers at Getaway Couple found each treatment holds odors down for up to a week, and a 30-pack lasted them over seven months of continuous travel — which puts the per-month cost near pocket change. The honest caveat is dosing: each pod is formulated for tanks up to 40 gallons, so owners of small or cassette tanks end up cutting packets open to split doses, which is awkward for a product whose whole pitch is convenience. The orange scent is present but mild — most owners count that as a feature.
Our verdict
An easy default for standard RV black tanks. Cassette-toilet and small-tank owners should pick a measurable liquid treatment instead.

Most praised
Owners praise dependable odor control between dumps and the zero-mess convenience of pre-measured pods that last months per tub.
Most common complaint
The fixed 40-gallon dose is the recurring gripe — wasteful or fiddly for smaller tanks — and some find the scent very faint.

Frequently asked questions
How often do you add a drop-in?
One pod after each time you empty the black tank, along with enough water to cover the tank bottom. One treatment is rated for up to seven days of odor control.
Is it septic safe?
Yes — the formula is marketed as septic-safe and biodegradable, so tanks treated with it can be emptied into normal dump stations and septic-connected systems.
Do the pods dissolve on their own?
Yes. Drop the sealed pod into the toilet with water and the wrapper dissolves — no cutting or measuring needed for standard-size tanks.
