STAR BRITE Aqua Water Tank & System Flush
Features describe deep cleaning and deodorizing of fresh water tanks and the entire drinking water system, with removal of scale and sediment that can cause foul tastes and smells. Best for: Boats or RVs preparing storage or after long seasons when tanks have sat idle. Caution: ensure thorough flushing after use to avoid any residue impacting taste.
Aquamarine Water Solutions – Shock
Designed to clean and deodorize fresh water tanks and systems, the formula is easy to apply by adding to the tank, circulating, and draining. Best for: Boats and RVs coming out of storage or starting a new season where tanks require a strong clean. Limitation: not intended for pools, septic systems, or wells, so use strictly within marine/household potable frameworks.

It also acts as an effective deodorizer and helps keep sensors accurate by preventing buildup near the sensors. Best for: Boats requiring thorough waste breakdown and reliable odor control. Caution: avoid overuse in systems with non-standard waste management configurations.
Buying Guide
- Tank type and size: Match treatments to holding tanks, freshwater tanks, or marine toilets. Some products target whole-system cleaning, others focus on odor control only.
- Storage seasonality: Consider products designed for post-storage cleaning or pre-season freshening. Deodorizers help during long-term storage and easy pump-out readiness.
- Water system compatibility: Potable-water additives should be compatible with drinking water lines. Avoid mixing products intended for septic systems with potable water lines.
- Ease of use: Pre-measured pouches or simple add-to-tank formats reduce maintenance effort. Some systems require recurrence to maintain efficacy.
- Sensor compatibility: If tank sensors are critical, choose products marketed to keep sensors clear of sludge and buildup.
- Limitations and safety: Review labeled cautions for use near drinking water, wells, or non-marine systems. Not all products are universal across boat sizes.
