It doesn't really work by a "Per gallon" dose.
You have to consider the current Bio-load vs. the oxygen demand and then go from there. You have to remember that there will be an increase temporarily in CO2 as respiration of the bacteria occur and that will help drive off O2.
The safest recommendation I would say is 2 tablespoons of sugar for a 100g tank.
DO NOT USE MORE!!!
For tanks between 55g to 100g use 1 tablespoon. If no cloud occurs within 48 hours you can then use 2 tablespoons.
For tanks under 55g, JUST DO THE WATER CHANGES!!!!!
This process can be deadly if done wrong!!!
Then after this first dose is done, if the tank was very cloudy for 3 days then the dose is working and should be done once a week with water changes. If there was no cloudy water you can increase by 1 tablespoon of sugar and try it again.
This is not an exact science and there are way too many variables from tank to tank so each one is an experiment on its own. BE CAREFUL!!!! BE PREPARED TO CHANGE WATER IF THERE IS ANY PROBLEMS!!!
Good Luck!
