Sodium carbonate works just as well as Calgon for the GEO method and is much cheaper. We've used it exclusively for 12 years in our RV's; no other chemicals. You can buy this at any WalMart in the CLEANING SECTION labeled as "Washing Soda". Arm and Hammer sells it right next to it's baking soda.
"Other Uses for Washing Soda
In addition to uses in the laundry room, washing soda also has other uses around the house. It is a good cleaner for cutting through baked-on grime in the kitchen, soap scum in bathrooms and unclogging drains. For cleaning, mix a solution of 1/2 cup of washing soda to one gallon of warm water. To unclog drains, pour one cup of washing soda into the clogged drain followed by two or three cups of boiling water. Allow the washing soda to work for thirty minutes and then flush the drain well with plain water."
