Holding tanks

[camp104]

Has anyone heard of putting fabric softener in the tanks for odor control. someone told me he uses it and his tanks never stink? TOM

Fabric softener will do nothing for odor. Fabric softener is used to make the water softer/slipperier so that the tank sensors work better.

The Geo Method

Search "GEO" method. Using water softener (Calgon), not fabric softener, and a little laundry detergent to help keep the tanks clean and odor free. Works well. Truth is, all you really need is lots of water and regular dumping.
