Bird,
Yep - that's the stuff. And I've used Rid-X also. I think that the Krane product may have more bacteria that the Rid-X.
Krane products is an interesting place. They call you just before your supply is supposed to be exhausted. Currently we have a 1,000 year supply of the stuff (based upon our usage!). Well, the last time they called us, the CFO negotiated the price down to 1/2 of the originally stated price. Want to know how to negotiate with these guys. Just keep saying, "No thank you!" and they'll keep on reducing the price. Either you give in and say yes, or they finally accept your no.
As for the recommended usage, we try to remember to put some in every once in awhile. Just to liven things up in the septic tank and to clean up the traps, drains, and pipes for the system. Effective - I guess. We've never had any problems with our system in the 11 year old system. Knock on wood.
As I've stated in some prior posts, we just had our system pumped for the first time and everything looked fine. We're very carefull on what we dump into the drain. Don't use many cleaning chemicals or bleach to foul the system. Hmmm - maybe that's why we don't have many friends. /w3tcompact/icons/wink.gif
