After joining and reading this great forum, I cleaned out the holding tank and began using no flex The waste level indicators were not working when I bought the boat 2002. With in the timeframe for the next pump out they began to work again. So I’m now a convert.After reading through many of these threads and coupling that with my experience with RVs and boats black tanks, these are my thoughts on the issue.
There are three ways to deal with waste in a black tank,
Preserve it, (formaldehyde) no longer an option.
Mask it, perfume it, liquefy it, most of the common tank treatments.
Use a biological component to create an ecosystem that naturally accomplishes the elimination of voters and the liquefication of solids.
My observation is that many of the strong supporters of no flex type treatments have newer boats that are under 20 years old. It may very well be that once the boat gets to a certain age and build up it may not work or may take a long time to get the system cleaned to eliminate the odor’s. Also it may be that chemicals used in the past on older boats leached into the materials of the system and are killing the biologicals...
I really do believe that the biological products work, and work very well.
If it is not working on your boat you probably have other issues,
need to use more product until years of build up or removed,
the oxygen supply for the bacteria is limited or blocked from the vent line,
there may be something in your tank or system that is killing the biologicals,
you are using a toilet bowl cleaner that is killing the bacteria,
set your expectations that this is not an quick perfuming job, this is building a living ecosystem that consumes the waste.
Additional issues affecting the product will be added to this post as they are posted.
