Customer Reviews
“★★★★★” “I like how simple this product is to use…you simply put a tablet of Elemonate in your sink, run some water on it til it washes down the drain, and it goes to work. I usually perform this operation before a trip so the chemical gets to work while I am using/filling the grey tank…in my experience, it does freshen your gray tank.”Oliver
“★★★★★” “These lemon grey tank packs seem to work well, they bubble up like hydrogen peroxide when they hit water, smell is good and no complaints from me. Grey tank is a grey area for me, you don’t really notice grey tank smells like a black tank, but grease and food can build up and these packs can keep tank fresh. I use a pack, fill tank with hot water night before I finish camping, so can dump next day and clear out any crud from trip.”rotwiler


“No need to measure out 8 ounces of liquid from a 32 ounce jar of holding tank treatment. These are a loosely formed briquet that smells “lemon fresh” and you simply drop one into the sink, run a little bit of water over it and that’s it. It melts down really fast and coats your drain pipes on the way down to the holding tank so that the whole system gets refreshed and deodorized. We like them well enough that we have now set up a recurring order and they ship some to us every few weeks.”



“Highly recommend these tabs for use in your grey water holding tank. Our tank started smelling like a sewer and we didn’t know why since grey and black water tanks are totally separate. Well come to find out that greases and food particles etc build up in your tank and cause odors. We use these each time we take our RV out and no more foul smells. These tabs cut the grease and clean the tank!”
