The Story
Unlike other nitrate reducing products, which need regular recharging and replacing, Tetra NitrateMinus is simply added weekly to the aquarium. Also unlike many ordinary nitrate reducing products, NitrateMinus does not need to be added to a filter system to work, but is simply added straight to the water.
NitrateMinus utilises a natural biological process called denitrification to remove nitrate. Under conditions of low oxygen, such as are found under the gravel in most aquariums, special bacteria use nitrate instead of oxygen to break down the NitrateMinus granules. By doing so, they steadily reduce existing nitrate levels, and maintain a permanently low level. In addition to removing nitrates, NitrateMinus also releases a low level of carbonates into the water, which helps to stabilise the pH of the water.
