The formula is gentle and effective, suitable for fish, plants and invertebrates, and promotes a healthy ecosystem in the aquarium. Its use method is simple: when algae first appears, add 2 capsules to 10L of water. After 3-5 days of continuous use, replace 1/5 of the water and add it again. When algae is serious, increase it by 2-3 times appropriately. When the algae is serious, it can be recycled in small batches. After 2 cycles of use, it can be used every 7-11 days.
