• Chlorine: use 1 measure to each 60 L (15 gallons*) of tap water (removes 1 ppm).
• Chloramine: use 1 measure to each 75 L (20 gallons*) of tap water (removes 1 ppm).
• Ammonia: use 1 measure to each 11 L (3 gallons*) of tap water (removes 1 ppm). Do not overdose!
For reference, 1 measure = 100 mg. To detoxify nitrite/nitrate in an emergency situation use up to 5 measures to each 40 L (10 gallons*). Use fish to gauge toxicity reduction as test kits will still show presence of nitrite/nitrate even when detoxified. May be added to aquarium directly, but is better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. If temperature is > 30 C (86 F) cut dosing in half.
