Pure water of a R.O. system is very soft and contains less minerals. For breeding tanks, soft water tanks (Amazonian aquaria) or for sea water it is useable without any further conditioning. For east African tanks (lake Malawi, lake Tanganyika, etc.) the water must contain more minerals and a higher pH value.
The AquaCare Mineral Filter is filled with calcium carbonate granules. If the water of a R.O. system is pushed through this filter the water will contain more calcium and more carbonate hardness - the pH value will be higher.
The hardenup-efficiency depends on:
- size of the filter
- the carbon dioxid concentratin of the pure water of the reverse osmosis unit and
- the flow of the reverse osmosis unit
