Such a system is highly practical to utilize for freshwater fish tanks, and it is crucial to use RO/DI system for combining saltwater and for refilling freshwater lost brought about marine tank evaporation.
A reverse osmosis water system is specifically designed to filter the water, particularly to eradicate any pollutants in order to have contaminant-free water effectively. This comes in distinct shapes, sizes and functionality. So, it is imperative to know what aquarium model you are currently keeping before you get one.
