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.

Marine salt for R/O and tap water Thanks to its outstanding homogeneity and uniform grain size, sera marin salt dissolves effortlessly and leaves no residue, creating crystal clear marine water. It maintains natural GH and KH levels while supplying ample calcium and magnesium in biologically appropriate proportions. The pH level is kept consistently within the ideal range due to the natural buffering system present in sera marin salt. Through a unique process, this salt retains trace elements in a manner that keeps them dissolved and available for an extended period. sera marin salt is free from any substances that could artificially boost protein skimmer performance. It is also devoid of nitrates, silicates, and phosphates. Sera (sea salt free of nitrates, phosphates, and silicates) provides calcium along with all the essential trace elements required for successfully cultivating ornamental algae and lower resins in saltwater. Additionally, it includes a blend of special substances that aid in the removal of harmful elements such as heavy metals and copper. It dissolves swiftly and without leaving deposits. With its natural buffering system, it guarantees a stable pH value. Instructions for use: Dissolve Sera marin salt (approximately 33 g per liter of water) to achieve a water density between 1.022 and 1.024 g/ml in treated water (osmosis) or chlorine-free tap water, aerate for 24 hours, or mix thoroughly with a submersible pump to enhance oxygen and carbon dioxide levels. Warning: Do not dissolve sea salt directly in an active aquarium! We suggest changing 5-10% of the aquarium water monthly, and using sera aquatan and sera bio reef clear for improved water quality. When establishing a new aquarium, treat the water with Sera aquatan and Sera bio reef clear, and allow the aquarium with all connected equipment (pumps, heaters, filter...) to operate for at least 14 days to achieve biological stabilization before introducing fish.
