API pH Up 118ml is a liquid pH adjuster designed to help you raise the pH level in freshwater aquarium water when it falls below the desirable range. Stable pH is essential for fish health and overall tank balance — and this easy‑to‑use formula lets you correct acidic conditions safely and effectively.
This clear, fast‑acting solution works by neutralising acidic substances in the water, making it more alkaline without adding colour, cloudiness, phosphates or nitrates — so your aquarium stays crystal‑clear and won’t be encouraged into unwanted algae growth.
Key Benefits:
📈 Raises aquarium pH: Helps correct low pH to suit the needs of your fish and plants.
💧 Fast‑acting and colourless: Works quickly and won’t cloud or discolour water when used as directed.
🌿 Safe for aquatic life: Phosphate‑free and nitrate‑free formula that’s gentle on fish and live plants.
🐠 Easy to use: Simply dose based on your tank volume, then retest pH before additional adjustments.
Ideal For: Freshwater aquariums where pH has dipped too low due to tap water, waste build‑up or biological activity — especially when specific species thrive better at higher, more alkaline levels.
Use with an API pH test kit to monitor and carefully adjust water chemistry for a stable, healthy aquarium environment.
