ACTIVE RV Black Tank Treatment is a concentrated 32oz enzyme and probiotic liquid that provides 16 treatments to digest waste, reduce odors, and help maintain RV black and gray water tanks.
When you’re on the road or on the water, reliable tank treatment reduces smells, prevents clogs, and helps sensors stay accurate. ACTIVE’s formula blends enzymes and beneficial bacteria in a compact bottle so you can pour 2 ounces per use and keep toilets, holding tanks, and gray water systems functioning more smoothly between dumps.
The product uses targeted enzymes to break down organic waste and probiotics to outcompete odor-causing microbes, which together reduce foul smells without masking them. It’s formulated to work throughout the holding tank so odors are minimized at the source rather than covered up.
Regular use helps keep sensor probes free from buildup and lowers the risk of pyramid plugs and clogs by liquefying solids. Because you add a measured 2-ounce dose per treatment, it supports consistent maintenance rather than drastic cleanouts.
Yes — the formula is suitable for black tanks, gray tanks, portable toilets, cassette systems and most marine holding tanks. It’s designed to be broadly compatible so owners of Airstream, Winnebago, Jayco, Thetford, Camco and other common brands can use one product across multiple setups.
ACTIVE arrives in a compact 32oz bottle holding enough concentrate for 16 standard 2-ounce treatments. Usage is as simple as pouring the recommended dose into the toilet or tank and flushing, making it convenient for weekend trips or longer adventures.
Who this is for: ACTIVE RV Black Tank Treatment is made for campers, RV owners, liveaboard boaters and anyone managing portable or cassette toilets who wants a practical, septic-safe way to control odors, reduce solids and maintain tank sensors. It’s a good fit for weekend warriors and full-time travelers who prefer a concentrated liquid solution manufactured in the USA and formulated for wide compatibility.
Q: How often should I add ACTIVE RV treatment?
A: Add one 2-ounce dose each time you flush or follow your travel frequency; regular dosing keeps tanks broken down and reduces odors.
Q: Is this safe for septic systems and campgrounds?
A: Yes. ACTIVE uses CA-compliant ingredients and is formulated to be safe for septic systems and standard campground wastewater practices.
