FishScience pH Reducer (250ml) – Safe, Gradual pH Adjustment for Soft Water Species Soft water species like tetras, discus, rasboras, and dwarf cichlids often come from naturally acidic environments – and replicating that in a tank with harder UK tap water can be genuinely tricky. FishScience pH Reducer is designed to bridge that gap, gradually lowering aquarium pH without sudden swings that could stress or harm your fish. Whether you're fine-tuning conditions for a soft water tropical setup or maintaining a planted tank where lower pH supports healthier plant growth, this product allows for precise, measurable adjustment – exactly the kind of controlled approach that good water chemistry management requires. Key Features & Benefits Gradually Lowers pH: Adjusts pH steadily, avoiding the sudden swings that can stress or harm fish. Ideal for Soft Water Species: Suited to tetras, discus, rasboras, dwarf cichlids, and similar species that thrive in lower pH conditions. Great for Planted Tanks: Supports the lower pH conditions that benefit many aquatic plants. Controlled, Measurable Dosing: Clear dosing guidance allows for precise, predictable pH adjustment. Suitable for Freshwater Aquariums: Formulated specifically for freshwater set-ups. Safe When Used Correctly: Designed for gradual use alongside regular water testing for safe, controlled results. Why We Rate This Replicating the natural water conditions a species evolved in is one of the more advanced parts of fishkeeping, and pH is often the parameter that needs the most careful attention – particularly for soft water species being kept outside their natural range. UK tap water tends to run on the harder, more alkaline side, which isn't ideal for fish that naturally come from soft, acidic waters like Amazonian blackwater habitats. What we'd really stress here is the importance of testing daily and adjusting gradually – sudden pH swings are far more dangerous to fish than a slightly elevated baseline pH ever would be. This product is designed with that gradual approach built in, but it still requires your attention and regular testing alongside it. Not a "set and forget" product, and it shouldn't be treated as one. Dosage Guide Add 5ml per 50 litres to reduce pH by approximately 0.1. Important: Test daily and adjust gradually. Never make large or rapid pH changes – consistent, small adjustments are always safer for your fish. Suitable For: Soft water tropical species including tetras, discus, rasboras, and dwarf cichlids Planted freshwater tanks requiring lower pH conditions Aquarists managing precise water chemistry Tanks needing gradual, controlled pH reduction Precise pH control, done properly – add FishScience pH Reducer to your basket today.
