I use a small digital postal scale, but before that used a weight watchers
scale. Just went and measured in a measuring cup and 500 grams of sodium
thiosulfate is almost exactly 2 cups.

Use 500 grams per gallon of
water and it will treat about 20,000 gallons of pond water.
=================
How do I measure grams without a gram scale? Using a tsp. would not be
accurate because of the density/weight of different substances.
