• Add 1 ml. for each 10 gallons or 5 ml. for each 50 gallons of aquarium water.
• Repeat dose every three days until algae is controlled.
• Siphon or scrape any dead algae from aquarium.
• Once algae growth is under control, add one dose per week.
• Weekly doses will control algae growth and reduce aquarium maintenance.
