Chemicals for Gray Tank
We use Thetford Campa Chem in our BLACK tank and looking to find what chemicals should be added to the GRAY tank to reduce odor.

To solve gray tank sensors' false readings and to remove the accumulated gunk inside, I've made my own mini flushing wand type thing which attaches to a hose and is inserted through the drain hole at the bottom of the tank. Works great!
