Soft water - but safely The pH and KH will decrease. Adjusts the carbonate hardness. Regulates the pH level. Creates soft and slightly acidic water suitable for various species. Certain fish species, such as discus and angelfish, thrive in very soft water, which is especially crucial for their breeding. Additionally, when breeding other fish types, the water may exhibit elevated carbonate hardness (KH) or the pH level might increase excessively due to natural metabolic processes. In these situations, sera pH/KH-minus provides a reliable and swift solution. The pH and KH levels decrease immediately and are effectively regulated. This establishes suitable conditions for rearing that enhance the vitality and overall well-being of the fish. Tip: Adjust the KH with sera pH/KH-minus to 4°dkH and then add sera super peat to the filter to maintain appropriate tropical soft water conditions for an extended period.

Bacteria and enzymes are ready to spring into action. Fish waste, leftover food, and decaying plants can quickly accumulate into a sludge layer at the bottom of your aquarium.

Sera filter biostart is the perfect companion for sera bio nitrivec, which begins its process immediately after sera filter biostart. Together, these two products work to ensure your aquarium water remains clear and healthy. With its high-performance filtration capabilities, sera siporax Professional creates optimal conditions for the effectiveness of sera filter biostart and sera bio nitrivec.

Stability and Certainty It provides a buffer and maintains the pH level. It also works against biogenic scaling and creates optimal conditions for specific species (such as African Cichlids). Carbonate hardness (KH) is among the less critical factors of aquarium water. Most freshwater fish thrive in water that is somewhat harder. Moreover, KH serves as a buffer that helps to avoid hazardous fluctuations in pH values, including sudden increases in acidity. For all community aquariums, it is advisable to maintain a minimum KH of 6°dkH, with even higher levels recommended for specific cases like African Cichlids. This ensures the health of the fish while keeping the aquarium water resilient and easy to care for. Sera KH/pH-plus effectively raises KH to the desired level in a precise and long-lasting manner. The pH level will rise gradually and, most importantly, it will be securely stabilized.

Stability and Assurance It provides a buffer and maintains the pH level. It also combats biogenic scaling and fosters ideal conditions for specific species (such as African Cichlids). Carbonate hardness (KH) is among the less critical parameters of aquarium water. The majority of fish in freshwater tanks tend to thrive in relatively hard water. Moreover, KH serves as a stabilizing buffer that prevents harmful swings in pH levels (including sudden increases in acidity). For community aquariums, it is advisable to keep a minimum KH of 6°dkH (even higher for specific species like African Cichlids). This helps ensure the health of the fish, while also making the aquarium water resilient and easy to manage. Sera KH/pH-plus will accurately and consistently raise KH to the desired level. The pH will gradually increase and, most importantly, will be safely stabilized.
