The stable residual and low aluminum corrosion rates make Clean Tabs Puriclean (far right) the PS Best Choice among tank sanitizing chemicals. Our Best Choice among tank freshening and disinfection chemicals are the Mega Tabs (far left).

Keeping Water Clean and Fresh

In the first part of our three-part series covering onboard water quality, we discussed protecting the tank with basic filtration and securing the tank vent. Further action is required, however, as the tank and its contents will always be far from sterile. Municipal water is filtered to remove turbidity, disinfected (typically with chlorine, ozone, or ultraviolet light), filtered once more (often very fine filtration to remove cryptosporidium cysts, which resist disinfection), and disinfected once more (with chlorine or chloramine) to protect the water while its in the distribution system. However, since we are storing the water on our boats, this process of secondary disinfection becomes our responsibility. So what are the options for treating water that is already in an onboard tank?

Note: This is a mock up to illustrate the tester placement, but this is a tester for a gasoline engine, not a diesel because it only goes up to 300 psi. A diesel tester would go up to 1000 psi. Also, ALL of the glow plugs should be removed, not just one. In addition, the hose is not actually screwed in because the fitting is the wrong size. (Photo/ Phil Decker)

Solutions for a Stinky Holding Tank

Practical Sailor testers looked at a large field of holding tank additives and found that chemical treatments that rely on disinfection, surfactants, and deodorants are better than nothing, but they still left that distinctive public-restroom smell. We also compared eight top-performing additives from a new generation of tank treatments that use enzymes and bacteria cultures to reduce odors. Tests showed that these bio-augmenting treatments—including Odorlos, SeaLand Max Control, Camco’s TST Citrus, Thetford Eco-Smart, Nature-Zyme, and Aqua-Kem—reduced odors and reduced solids in the tanks, without the port-a-potty smell. We look at the pros and cons of these newer tank treatments, and examine the importance of tank ventilation in reducing odors.

Irwin Citation 34 Used Boat Review

The Irwin 34 is in many respects a typical Irwin boat. It was originally called the "Citation 34," which was meant to indicate that it was more of a plush cruiser than the race-oriented Irwins at the time, but more of a racer than the larger cruisers. According to the company, 305 Irwin 34s were built in the production run, from 1978 to 1985, a moderate but successful model for the era. Near the end of its production, the boat was advertised as the Irwin 34 rather than the Citation 34. There were no major changes in the boat from beginning to end, just the details and equipment that are typical of any long production run.
