Seachem Acid Buffer: pH Control for Freshwater Aquariums
Seachem Acid Buffer is an efficient solution for safely lowering and stabilizing the pH in freshwater aquariums. It is designed to convert alkaline water conditions to more acidic levels without using phosphate-based ingredients, which can contribute to unwanted algae growth. This makes it ideal for fish species that thrive in slightly acidic water environments, such as tetras, angelfish, and other soft-water species.
Key Features:
- Lowers and stabilizes pH: Adjusts pH levels in a controlled manner, ensuring a stable environment for sensitive species.
- Phosphate-free formula: Prevents algae blooms by avoiding phosphates, which are often a byproduct of other pH-adjusting products.
- Works in combination with Seachem Alkaline Buffer: Provides comprehensive pH control when used together, allowing for precise management of pH levels.
Dosage Instructions:
- Standard dose: Use 1 gram (approximately ¼ teaspoon) for every 80 liters of water daily until the desired pH level is achieved. The product can be dissolved in water before adding to the tank, or added directly.
Sizes Available in Australia:
Seachem Acid Buffer is available in various sizes to meet the needs of different aquarium setups:
- 70 g – Ideal for small tanks or occasional adjustments.
