How to Use

1. Determine the water volume of your aquarium.
2. Add one piece per 20 litres of water, or one complete block for up to 120 litres.
3. Place the appropriate amount into the aquarium.
4. Allow the block to dissolve naturally over approximately 7–14 days, depending on water conditions and circulation.
5. For best results, reduce excessive sunlight or artificial lighting where possible to help slow algae growth.
6. Remove heavy algae growth mechanically before treatment where practical.
7. Aerate the water after use, particularly when there is significant algae growth, to help prevent oxygen depletion.
