The hardness of water is the amount of minerals dissolved in it. If the amount of dissolved minerals is high-the water is hard, if low-then soft.
Water hardness increases when filtered through porous rocks such as chalk or limestone. Signs of high rigidity is the formation of lime plaque on pipes, taps and inside kettles, as well as the formation of foam on the water when adding soap. Hard water is found in areas such as lake Malawi, where fish are adapted to high hardness and pH levels.
Limescale and soap suds do not form in soft water. Soft water flows over hard rocks, such as granite, or through fallen leaves and peat, from which minerals are almost not washed away. Continue reading
Fashion to breed fish in aquariums appeared not so long ago, and the specifics of this activity still requires study and practice. All types of aquarium fish have ancestors who lived in natural conditions, so to create them at least artificially such conditions is the primary task of any aquarist seeking to extend the life of their Pets.
What affects the life span of fish
No matter how much we take care of the fish, they still die of old age one day. Continue reading
