Amount of TH Marine Minnow Maker?

The instructions on the one ounce bottle I bought says to mix 1 oz to 90 gallons of water or eight drops (1ml) to a standard size bait bucket. How many gallons is a do you consider a standard size bait bucket to be? I have a 10 gallon container for keeping minnows in and need to know the proper amount to add to that as well as the proper amount to add to 2 gallons for when I replace water every few weeks. Thanks!
