Valterra V77012 Odorlos Dry 6 Lb Tub

Switched to this product instead of the blue liquid from chain marine supply store. Works perfect no stains from blue dyed. It's a white powder with a scoop.

I have used this for the past few years on our 39' trawler (motorboat) in a 40Gallon black water tank. The tank is fitted with a good vent that is needed in order for this material to work properly. Using Odorlos has prevented the dreaded passed gas stink outside of the boat when the head (toilet) is flushed by someone below.Definitely recommend this material. Watch the product video to understand how it works. I put 2 scoops in the head and flush it with plenty of clean water after it dissolves (takes about 5 minutes) to treat the 40 gallon black water tank. I add new Odorlos every time we pumpout the tank so that material is available to treat the new contents. One 6Lb bucket lasts an entire summer of boating but extended travel on board may require two to get through a long season of travel.

No smell. Easy to use.

No odor. Dissolves well never any smelly issues with black tank.

4th time ordering this product. UPS LOST IT.I use it in TT. Very good product. Will reorder.
