A larger-package example
For 30 US gallons using the larger-container chart, maintenance works out to 6 fl oz and clean-up to 12 fl oz. These are arithmetic examples from that chart, not small-bottle directions.
Do not generalize a bottle count
One bottle is only meaningful when the size and instructions are specified. Write both the product and package on the fill note. This prevents an instruction from becoming ambiguous when someone buys a different container.
Keep purpose separate from symptoms
Use the label's intended treatment categories. Do not assume that an unexplained running problem calls for a stronger dose. Persistent symptoms should be assessed, and the treatment plan adjusted according to guidance rather than guesswork.
Check the official directions
Use the current package label and manufacturer documents for treatment rates, handling and application details.
