Any recommendations for an enzyme based black tank treatment that has no added scent? My favorite, Thetford Ecosmart, is out of stock everywhere. I suspect the bots sensed a shortage, bought it all up, and it's now $29 per quart.
And I thought paying $6 CDN for a quart of whipping cream during this pandemic was bad! GK
I found good reviews for Walex Bio-Active liquid and it's available for reasonable prices at several RV suppliers. I ordered a half gallon which will be enough for this season.
The Thetford stuff I mentioned in the first post is back in stock in some places, but now more than twice the cost of the Walex.
We use Happy Campers Organic Odor Free.
Tanks are clean and no odors.
