Its not that mysterious! For a 10% solution, 0.34 ml is one ppm for 10 gals. One ml is 1 ppm for 30 gals. And so on. here's the math:
All Glass “10 gal” tank, fill to bottom of black trim:
Internal Dimensions: 11inches by 9.75inches by 19.5 inches =
27.94cm x 24.765cm x 49.53 cm = 34271.5 cc = 34.27 liters
or L in x W in x H in x 2.54 cubed (16.387)
Ace Hardware Ammonium10% sol =100grams per liter (or kilogram) = 0.1 grams per ml = 100 mg per ml (remember, an ml of water and a gram of water are the same)
1 ppm is 1 mg per liter (1gram per 1,000,000cc = 1gram per1000Liters =1mg per 1 Liter)
34.27liters x 1 mg/L is 34.27mg in the whole tank filled to bottom of black trim.
34.27mg / 100mg/ml = .34 ml in the tank for 1 ppm.
So yeah, 3 or four drops per gallon is more like 10 to 15 ppm?
