Designed specifically to reduce ammonia and nitrate, improve water quality, and maintain the healthy balance of aquatic organisms. The usage method is extremely convenient: For daily algae removal, add 10 milliliters of this product to every 100 liters of water. First, dilute it with the water in the aquarium, then pour it evenly. Use it every other day for 2-3 consecutive cycles. Prevent algae growth: Add 30 minutes before each water change, 5 milliliters per 100 liters of water. This helps to inhibit the growth of new algae.
