Calgon Water Softner is a liquid that you can get at WalMart, Walgreens, Amazon and other places. It's sometimes hard to find. It makes the water in your tank "slick". The thought process is that things like toilet paper and other "matter" will not stick to the sides and sensors
as easily. I use one capfull in every tank just after I dump, then add one Enzyme tablet and two gallons of water. Does it work? It does for me
