RaritanK.O. Kills Odors Bio-Active Treatment - Gallon

Works like a charm. No brainer. Much better than that blue stuff.

I love this stuff. It's biological and it keeps the odors away. I use it in combination with the Raritan C.P. and put the K.O. in every time I start a new tank. No bad smells at all!

REALLY WORKS...Very expensive but I can get 3-4 month of continual use and if you dont use any other cleaners it does what it says. Absolutely no small even during pump out.

Used this on our boat several years ago. Now trying it in our rv. Not as good in RVs , after two days seems to loose its potency

This is the very best chemical for houseboat holding tanks. We've been using it for many years.

Works great. We use it in the blackwater tanks on our boat. It isn't cheap but it works. This is an organic enzyme product. Don't use any Clorox/chlorine products. Clorox kills the enzyme action.

Great product for my houseboat
