XEPTA Mg+ 850g Magnesium is a fundamental element in maintaining the balance between calcium and alkalinity. It is necessary to maintain an appropriate calcium level in our aquarium to keep magnesium levels between 1290 and 1350 ppm, and vice versa. If magnesium is below 1290 ppm, it becomes challenging to maintain the calcium level at 420 ppm. Achieving the correct balance of...
