Depending on shape and the contents of the bucket there is a formula you can use to figure out the number of oxygen absorbers you will need.
18,492 cc is the amount of empty space in a 5 gallon bucket. Weigh the contents for the bucket and convert it into grams. If you need help just look up a conversion table online for converting ounces to grams. If weighing the contents inside the container be sure to subtract the weight of the container to get the net weight of the contents.
Subtract the volume of the container itself (18,492cc) from the gram weight (contents) to get the residual volume or space that will be left over between the contents and the 5 gallon container.
The air has about 20.5% of oxygen so times the residual air volume (leftover space) by .205 to get the cubic centimeter volume of oxygen in your container.
Oxygen absorbers come in different absorbant capacities and are also labeled differently as such. One you know the amount of oxygen you will have in the bucket you can then select a suitable size or use several to fit the requirement.
