The Calcium Problem

Everyone who owns or operates a boat with a seawater toilet knows about The Calcium scale Problem. Urine mixes with saltwater in the toilet and produces calcium scale that builds up in the lines, fixtures and holding tank. Not only is this a major source of odor, it is a major maintenance expense, costing hundreds to thousands of dollars to service and replace components in the plumbing system.

A fairly standard way of trying to combat this problem involves flushing the holding tank with bleach on a weekly basis. While helping somewhat in reducing the odor it does not remove or reduce the calcium scale. Chlorine in bleach is sodium hypochlorite. The pH is around 12, too base to remove the calcium.

Our tablets are more acidic and it is this acidity that is responsible for removing and preventing calcium buildup, similar to the way vinegar removes calcium scale from your shower head at home. With The Commod-er-izer™ each flush introduces a minute amount of deodorant throughout the entire plumbing system, removing and preventing scale buildup and eliminating odors.

The photos below clearly show the results. The plumbing lines were inspected after one year from two boats that were placed in charter service at the same time from the same base.

– only a stain, no calcium buildup.

Financially speaking, since our system solves the calcium problem, The Commod-er-izer™ isn’t an expense but a savings. The cost of the unit is recovered after a few months and then continues to save you money, while eliminating the odor problem.
