Les 10 meilleurs pH and KH adjustment en 2026

TETRA - pH/KH Minus - 250ml - Safe reduction of pH and KH

TETRA pH/KH Minus 250 ml is a solution designed to easily and gently adjust water parameters in a freshwater aquarium. This treatment helps lower carbonate hardness (KH) , which also leads to a gradual decrease in pH, resulting in water better suited to certain ornamental fish species. It is particularly suitable for tanks requiring softer water, with a KH around 4 °dH and a pH below 7.5 . Its measuring cap allows for practical and precise use, whether for occasional adjustments or regular maintenance. It's a simple addition to any maintenance routine to keep the water more stable and consistent with your fish's needs.

• Gradually reduces KH to help achieve softer, better-balanced water.
• Promotes a controlled decrease in pH for conditions suitable for freshwater fish.
• Simple dosing with measuring cap for precise and regular aquarium maintenance.

Acid Buffer™ is a phosphate-free buffer for lowering pH and buffering with Alkaline Buffer™. Adjusts the pH from 5 to 8.

Discus Buffer® is designed to replicate the natural environment of Discus (low pH and low GH (total hardness)). Discus Buffer® will lower the pH and keep it lower. It is packaged based on phosphates and is free of carbonates. It will also soften water by removing calcium, magnesium, and other divalent cations.

SEACHEM Tanganyika Buffer (250g) helps improve the cichlid environment by increasing water hardness, buffer capacity and regulating pH between 9.0 and 9.4.

One year combo alert from Seachem combines a one year supply of Ammonia Alert® (1 card) and pH Alert® (1 card and 1 replacement sensor).

SEACHEM Tanganyika Buffer (500g) helps improve the environment of cichlids by increasing water hardness, buffer capacity and regulating pH between 9.0 and 9.4.

American Cichlid Salt is a chemically sound blend of salts designed to replicate the natural environment of American Cichlids. It contains all physiologically essential elements such as magnesium, calcium, sodium, potassium and includes trace elements such as iron, aluminum and iodide. American Cichlid Salt is formulated so that dosages vary depending on the origin of the species and should only be added when setting up an aquarium or during water changes.
