• Use Instructions: It is a violation of federal law to use this product in a manner inconsistent with its labeling. Before applying, first remove as much algae as possible by cleaning the glass and decor. This allows tetra algae control to be its most effective at reducing the remaining algae and inhibiting new algae growth. Remove activated carbon filters for 6-8 hours after dosing. Be prepared to clean out additional algae as it is killed to prevent deterioration of water quality.Apply dosage in the morning: Add 1ml of tetra algae control for every 12 gallons (45L) of aquarium water. Do not overdose. Adding tetra algae control in areas of high water agitation or by pre-diluting tetra algae control in a cup of aquarium water will help to distribute the active ingredient. Ensure the aquarium is well aerated. Repeat if needed every three days for up to three total doses, then clean the aquarium of dead algae, and do partial water change. For regular maintenance, use as algae starts to reappear.Attention: do not use in newly established aquariums less than three months old.
