Seachem Acid Buffer – 70 g Non-Phosphate pH Reducer for Freshwater Aquariums

Seachem Acid Buffer – 70 g Non-Phosphate pH Reducer for Freshwater Aquariums

Seachem Acid Buffer (70 g) is a phosphate-free formula that safely lowers and stabilizes pH in freshwater aquariums. It’s perfect for aquariums with soft-water fish and live plants that thrive in slightly acidic conditions—such as Discus, Angelfish, Rams, and Tetras.

Unlike many pH-adjusting products, Acid Buffer will not introduce phosphates that can encourage algae growth. When used in combination with Seachem Alkaline Buffer, aquarists can precisely set and maintain a desired pH while stabilizing carbonate hardness (KH) for healthy biological balance.

💧 Key Features:

• Safely lowers and stabilizes pH in freshwater aquariums
• 100% phosphate-free—safe for planted tanks
• Works with Seachem Alkaline Buffer for total pH control
• Ideal for soft-water species and live plants
• Provides stable, consistent water chemistry

📦 Product Details:

• Size: 70 g
• Type: pH-lowering powder (acidic buffer)
• Safe For: Freshwater, planted, and shrimp tanks
• Manufacturer: Seachem Laboratories

💡 Directions for Use:

1. Add ¼ teaspoon (2 g) for every 40 L (10 US gallons) daily until desired pH is reached.
2. For fine-tuning, use together with Seachem Alkaline Buffer in varying ratios to achieve a specific pH level.
3. Always monitor pH and KH levels after dosing.

Frequently Asked Questions (FAQ):

Q: What is Seachem Acid Buffer used for?
A: It lowers and stabilizes pH by converting carbonate hardness (KH) into available CO₂ for plants.

Q: Is it safe for planted aquariums?
A: Yes—it’s phosphate-free, making it perfect for planted and shrimp tanks.

Q: What’s the difference between Acid Buffer and Discus Buffer?
A: Acid Buffer is phosphate-free and adjustable, while Discus Buffer is phosphate-based and targets a set pH range (5.8–6.8).

Q: Can I use it with tap water?
A: Yes—it works with tap, RO, or DI water.

Q: What pH range can I achieve?
A: Alone, it can lower pH into the mid-5s; when paired with Alkaline Buffer, you can set any pH between 5.0–8.0.
