TREATMENT: On initial use or after a major (> 40%) water change, use 1 capful of Flourish Excel (5 mL) for every 40 L (10 US gallons). Thereafter, use 1 capful for every 200 L (50 US gallons) daily or every other day. For smaller dosing please note that each cap thread is approximately 1 mL.
SAFETY: Flourish Excel is completely safe for fish, however if you have Anacharis in an aquarium in which you are dosing Flourish Excel, then it is recommended to use it every other day rather than daily.
