Achieving the correct water parameters is crucial for maintaining the good condition of fish and plants in our aquarium. Products for changing water hardness are among the key products to ensure conditions that are closest to natural ones. For most species, the best water hardness is that with a parameter of 16 °d, which means moderately hard water.
