In a limited living space like an aquarium, essential minerals are often in short supply. Some of these important substances are absorbed by fish not through food, but directly from the water.

Whether the source water is already low in minerals, especially osmosis water, or whether a dense or particularly demanding stock depletes the desired resources, dangerous deficiencies can arise when vital substances are lacking.

The excellently water-soluble Sera Mineral Salt specifically provides all important trace elements as well as valuable calcium, magnesium, and potassium in pure form without harmful additives.

Tip: Due to its KH-neutral behavior (only slightly increasing GH while not affecting KH), Sera Mineral Salt can also be easily used in soft water tanks, such as those for discus fish. It also serves as protection against the dreaded hole disease.

Application: Normal dosage: 5 g/100 l of water. Soft water (e.g., discus tanks): 5 g/50 l of water. Hard water:.
