Same experience here as others. I dose it right to the tank as im filling. for 100 gallons you use 1/4 teaspoon. For smaller tanks ive got much smaller measures. Really last a lot longer. the 2.2 lb (1kilo) bottle treats up to 200,000 gallons and will last you years in most cases. Also detoxifies Nitrite, Nitrate and Ammonia. Removes Chlorine and Chloramine. I paid $24 US for my bottle and I have close to 18 running tanks currently.
BTW its not meant to mix with water to make a prime fluid. Its meant to dose dry.
