AF Minus pH

250ml

Maintaining the correct pH level is foundational for the health of both fish and plants. AF Minus pH helps achieve this by safely lowering the water’s pH to replicate the slightly acidic conditions preferred by many species — particularly those from soft-water biotopes like the Amazon. The formula contains no phosphates and is designed for gradual adjustment rather than rapid shocks, ensuring biological balance and reducing stress on aquarium inhabitants.

Key Benefits:

• Lowers pH in a controlled, predictable manner.

• Ideal for fish and plants from acidic-water habitats.

• Phosphate-free to help prevent algae growth and maintain clear water.

• Designed for use in water changes or preparation of replacement water.

Usage Guide:

• Preparation outside the aquarium: Do not add directly to the tank.

• Mix in water set aside for a water change, then add this treated water back gradually.

• Example dosage: 1 ml per 1 L lowers the pH by approximately 0.2.

• Do not lower the aquarium’s pH by more than 0.5 units in one day to avoid stress. 

• Store in a cool place, protect from direct sunlight, and keep out of reach of children.

Whether establishing a new biotope or fine-tuning a mature tank, this product is an essential tool for balanced water chemistry and thriving ecosystems.
