How Much Calgon ?
We have a 45 gallon black tank. How much Calgon (Water Softner) do you use in yours to keep things running well?

I pour 2 cups of calgon & a cup of liquid soap into a gallon jug, then fill with water. Then pour about 1/4 to 1/3 of the gallon solution into the commode to flush into the 30 gallon black tank, use tank til 2/3 or more full, dump and start over again. I also pour some into the grey tank after about every 3rd dump.
