pH Reducer, designed by FishScience, gradually lowers aquarium pH without sudden swings, helping create more suitable conditions for soft water species such as tetras, discus, rasboras, and dwarf cichlids. Safe when used correctly, it allows precise water chemistry adjustment. pH is one of the most important parameters in any aquarium, directly influencing fish health, biological stability and the effectiveness of natural metabolic processes. Even small pH shifts can represent significant chemical changes within the water due to the logarithmic nature of the pH scale. Fish Science pH Reducer is formulated to gradually lower aquarium pH without causing sudden instability or dangerous fluctuations that can stress fish and invertebrates. This controlled approach allows aquarists to fine-tune water chemistry safely while maintaining long-term stability within the aquarium. Different fish species naturally thrive under different pH conditions. Soft water species such as Cardinal Tetras, Discus and Apistogramma generally prefer more acidic environments between pH 6.0–6.5, while livebearers and African cichlids typically require more alkaline conditions. Understanding and controlling pH is therefore essential for recreating suitable biotope conditions and supporting natural behaviour, colouration and health. Fish Science pH Reducer is ideal for aquarists looking to safely lower pH in planted aquariums, tropical community tanks and specialist soft water systems. When combined with proper KH management and regular testing, it allows precise control over aquarium chemistry. Product Highlights: Gradually lowers pH safely Helps avoid sudden stress-causing swings Ideal for soft water tropical species Suitable for freshwater aquariums Controlled, measurable dosing Dosage Instructions: Add 5ml per 50 litres to reduce pH by approximately 0.1. Test daily and adjust gradually.
