sera pH/KH-minus

Soft water - but safely

  • Lowers pH and KH
  • Adjusts the carbonate hardness
  • Regulates the pH value
  • For appropriate soft and slightly acidic water


Some fish species (e.g. discus and angelfish) are adapted to very soft water and require these conditions in particular for reproducing. However, the water can provide too high carbonate hardness (KH), or the pH may have risen too strongly due to natural metabolism processes, also when keeping other fish species.

In these cases, sera pH/KH-minus provides reliable and quick support. The pH value and the KH are immediately and precisely lowered and regulated. This creates appropriate keeping conditions that considerably contribute to the vitality and the fish doing well.

Tip:
Adjust the KH to 4°dKH with sera pH/KH-minus and subsequently place sera super peat in the filter for permanently maintaining tropical softwater conditions.


Recommended dosage

For lowering the carbonate hardness (KH) by approx. 1°dKH daily, add 5 ml sera pH/KH-minus for every 5.3 US gal. (20 l) of water

  • for lowering KH and pH
  • for immediate help in case of acute intoxications by ammonia
  • for preparing the application of sera super peat (adjust KH to 4°dKH with sera pH/KH-minus, then establish permanently stable soft water conditions with sera super peat)

Daily repeat the dosage until the desired result is achieved. Do not add more than the double dose per day, as sudden KH changes by more than two degrees are not tolerated by all animals! Aerate the water well during application. Do not let the KH sink below 3°dKH (monitor with the sera kH-Test), as otherwise there is the risk of suddenly sinking pH values!
