Thetford AquaMax® Holding Tank Treatment - 6-Pack - 8oz Liquid - Spring Shower Scent

The Thetford AquaMax® Holding Tank Treatment in Spring Shower Scent is a marine-grade biological additive designed for managing waste breakdown and odor control in boat holding tanks. This product is essential for serious boaters who prioritize proper holding tank maintenance, as it protects plumbing, enhances crew comfort, and maintains resale value.

This 6-pack of 8oz liquid bottles provides a year-round supply for regular treatment cycles, making it an economical choice for recreational fishermen, liveaboards, and commercial operators. AquaMax® formulations utilize enzymatic and bacterial cultures to actively digest solid waste and break down organic compounds, effectively reducing tank sediment and minimizing unpleasant odors.

Boaters with both freshwater and saltwater systems can benefit equally from this treatment, which works across all marine sanitation device (MSD) types. Simply dose the holding tank weekly or after pump-outs for optimal results. The Spring Shower Scent variant adds a fresh fragrance that masks residual smells while the biological action does the real work.
