If you add it to 60 gallons of water, 60 gallons * 3.78 L / gallon = 226.8 L
0.6 grams / 226.8 = 0.26 mg/L
5 mL in 10 gallons: (Still 0.26 mg/L since the solution volume and tank size are both 5 times smaller)
(2 grams / 100 mL) * 5 mL = 0.1 grams in 5 mL of the 2% solution.
Adding it to 10 gallons = 37.8 L
0.1 grams / 37.8 L = 0.26 mg/L |
Cool, I was right; though I see I took a more complicated path to get there. As for the calculations for 10 gallons, I was assuming 8.5 gallons since the standard 10 gallon tank is only about 8.5.
Allan, could you share where you ordered it from since obviously you had a safe and easy transaction?
