Description
SWEETANK Odor Neutralization System - 12V THE CONCEPT The SWEETTANK concept has been developed to stop odors in yacht and RV holding tanks without the use of chemicals or filters. SWEETTANK is standard equipment on THERMOPURE-2 Type-I MSD, in GROCO Type-III MSD, and is offered in several retrofit kits to fit existing holding tanks.
HOW IT WORKS Aerobic and anaerobic bacteria coexist naturally in raw sewage, but it is the anaerobic bacteria that produce undesirable odors. By inducing a constant flow of air into the holding tank through a submerged aeration tube, SWEETTANK produces an oxygen-rich environment in which the anaerobic bacteria cannot thrive, thus eliminating unpleasant odors.
The heart of the SWEETTANK system is a compact module that operates continuously to deliver air to the holding tank using less than 3-watts of DC power.

Marine Plumbing & Ventilation — frequently asked
- How do I size a bilge pump?
- Bilge pumps are rated in gallons per hour (GPH), but actual output is lower once you account for hose length and vertical lift. Choose a pump rated well above your expected worst-case water intrusion, and consider a second, higher-capacity pump plus a float switch for automatic operation.
- Can I use regular garden hose for my boat’s water system?
- No. Marine plumbing uses purpose-built hose rated for the specific system — potable water, sanitation, and raw-water/bilge hoses differ in pressure rating, temperature resistance, and permeation. Using the wrong hose causes odors, leaks, or contamination.
- Why is ventilation important on a boat?
- Ventilation clears moisture that causes mildew and rot, and — critically on gasoline boats — clears fuel vapors from the engine compartment before starting. Blowers, cowl vents, and dorade boxes keep air moving through cabin and engine spaces for safety and comfort.
