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.
