ADA Soft Water makes the water slightly acid. Most aquarium plants and tropical fish prefer slightly acid water (pH<7.0). Ordinary tap water is often, however, mild-alkaline (pH>7.0) and is therefore less suitable for fish and plants. Soft Water reduces the pH and carbonate hardness (KH) and transforms the water to slightly acid.
In alkaline water with high level of pH or Carbonate Hardness (KH), the growth of aquatic plants gets inhibited. Soft Water adjusts the water quality to mild acidity.
Usage : Dose 1 ml per 10 litres aquarium water a week after the water change.
