Does anyone know what is in this product is or, of an equivalent product?
Black tank monitor starting flashing and then the system just stopped reading - no check no led light. I had a bottle of this holding tank enzyme treatment sitting around for a few years so I put some in when we got to the park. After a couple of days the black tank LED has started reading again.
I think the treatment (called QZ4 Quadra-zyme) may have actually worked. I remember buying it on clearance at the Gainesville FL Airstream dealer many years ago. Dealer had put his brand name on it (J.D. Sanders).
A Bing search on "Quadra-zyme" only came up with this dietary enzyme product
. I guess it could be the same stuff
below came up on the search too. Anyone use it?
