Ok here goes nothing. I figured it out to be about two teaspoons to fifty gallons. A teaspoon of sugar being about 4 grams & an ounce is 28.34 grams . An ounce treats about 204 gals so a 1/4 oz should do about 50 . So here Are the before pictures .Ill wait ten days , do a second treatment & post some progress pictures. Any support or ideas feel free to post . Thanks.
