Aquascape Once-a-Year Fertilizer has a long shelf life and will not degrade until it comes into contact with water. When stored in a cool, dry place, it will remain effective for several years. It is essential to keep the capsules or granular fertilizer completely dry, as exposure to moisture will begin to dissolve the outer coating.
Proper storage away from humidity and direct sunlight will ensure the product will be usable and maintain its full nutrient value over time. Store the fertilizer in its original sealed bag or an airtight container. Keep it in a dry location, away from moisture, high humidity, and direct sunlight to prevent clumping or premature breakdown
