API Water Softener Pillow Size 5

The Simple Solution for Soft-Water Success

Hard water can be a major hurdle for hobbyists keeping sensitive Amazonian or Southeast Asian species. The API Water Softener Pillow uses a high-grade ion-exchange resin to remove calcium and magnesium, the minerals responsible for "hard" water. By simply placing this pillow in your filter, you can create the ideal environment for fish that thrive in low-GH (General Hardness) conditions.

Why Your Aquarium Needs a Softener Pillow:

• Promotes Natural Behavior: Soft water is essential for the health and spawning of sensitive species like Discus, Tetras, and Angelfish.

• Eliminates Mineral Buildup: Reduces the "white crust" (calcium scale) that forms on your aquarium glass, lids, and equipment.

• Ion-Exchange Technology: Contains a specialized resin that swaps calcium and magnesium ions for sodium ions, effectively lowering water hardness without dramatic pH crashes.

• Rechargeable & Economical: This isn't a one-time-use product. Once the resin is exhausted, it can be easily recharged using a simple salt solution (API Aquarium Salt), allowing you to use it over and over again.

• Size 5 "Universal" Fit: Designed to fit perfectly inside most canister filters, power filters, and sump systems.

Perfect for Specific Water Needs:

• Amazonian Setups: Replicates the naturally soft, acidic waters of the Blackwater tributaries.

• Breeding Projects: Many egg-scattering fish require soft water for successful fertilization and fry development.

• High-Hardness Areas: A lifesaver for hobbyists living in regions with "liquid rock" tap water.

How to Use:

1. Rinse: Rinse the pillow under tap water to remove any dust.

2. Place: Insert the pillow into the path of water flow in your filter (after the mechanical filtration).

3. Monitor: Use an API GH Test Kit to monitor hardness levels.

4. Recharge: When GH begins to rise, soak the pillow in a solution of API Aquarium Salt for 2 hours, rinse, and place back in the filter.
