We were advised, and used this product with a new septic system back when we lived in a stick house in the country. I think the concept was to assist in breaking up kitchen (garbage disposal type) waste in one's septic system. Was not just to 'seed' a new system, but strongly recommended to use on a regular basis.
Was intrigued when this came up in another thread, and am curious how many of us (full-timers or not)use a wee-bit in their RV holding tanks like dalsgal?
FWIW, I've researched the topic of Rid-X some, as it applies to its intended use in home septic systems, and have found that the authorities (such as the water quality folks in various states) have different opinions, some saying it's harmful and never use it and others saying it's beneficial. So take your choice of advice. I suppose a small amount in your black tank won't cause much harm and might help something.
As to the idea of "sterilizing" your tanks, I agree that it's probably not a great idea, just like constantly "sanitizing" your kitchen counters is also a bad idea, not to mention ineffective in the first place. My reaction to the OP is that the guy he met in the Wal-mart (and/or his wife) is a bit "anal." Life is not about everything being neat and pretty and safe at all times, and certainly RVing entails some personal involvement with certain processes that at home are taken care of for us and seldom enter our minds. Part of the charm????
As for me, I just make sure there's a decent amount of water in the black tank when I dump, and let it go at that. We get a little odor from time to time, and when we do my wife, bless her heart, calls that to my attention, sometimes with vigor, so I pour in some blue stuff but no big deal. But then I grew up on a farm, and thus shoveled lots of poop in my day, so maybe one's view of all this depends on where one is coming from.
