The pool shops should have 1 pound bags. Weight calculations are easiest and best. Here is a formula
gallons of water x .0038 x desired ppm / dec. value of active ingredient of chemical = grams of chemical
100 gal x .0038 x 200ppm divided by .70 = 108.57 grams divide that by 12.78 grams per tablespoon = 8.49 tablespoons in 100 gallons of water.
It's hard to get it into solution quick, so you may need to recirculate in your tank. 200 PPM was the standard we used to disinfect tanks when I run the hatchery. I suppose you could use more to compensate for not getting it dissolved well. Maybe Dr Tim has a suggestion. We would let it set in our tanks recirculating for an hour
