The API Water Softener Pillow is a highly effective filter media designed to create and maintain ideal soft water conditions in aquariums. These convenient, ready-to-use pouches contain specialized resins that actively remove undesirable calcium, magnesium, and soluble heavy metal ions, including common contaminants like copper and iron, ensuring a healthier environment for sensitive aquatic life.

Each pillow provides active water softening for up to 48 hours before requiring regeneration. Recharging is a straightforward process: rinse the pouch, then soak it for two hours in a solution of three tablespoons of API Aquarium Salt dissolved in seven ounces of tap water. For optimal longevity, store the pillow in its recharging solution when not in use, preventing it from drying out. Replace the pillow when its effectiveness diminishes after recharging.

This product is an excellent choice for reef keepers and freshwater enthusiasts aiming to achieve or maintain precise soft water parameters. By consistently removing hardening minerals and potentially toxic heavy metals, the API Water Softener Pillow helps prevent issues associated with hard water, supports the well-being of inhabitants, and contributes to a more stable and pristine aquatic ecosystem.
