In a limited living space like an aquarium, essential minerals are often in short supply. Fish absorb some of these important substances 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: Sera Mineral Salt can also be easily used in soft water tanks due to its KH-neutral behavior (only slightly increasing GH, while KH remains unchanged), for example in discus keeping. This 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:.
