What is a Reverse Osmosis Water Filter System?
Reverse Osmosis is a process whereby water is purified as the water gets pushed through some sort of membrane. The membrane traps the impurities and they can remove 90% – 99% of the impurities from the water. The type of membrane you use determines the amount of impurities that the RO unit will remove. Our drinking water often includes minerals, heavy metals (mercury, copper), phosphates, nitrates, pesticides and herbicides (from farming and lawn fertilizers), chlorine and chloramine. These can all be potentially harmful to your fish. However, most municipalities do a decent job of eliminating most of these impurities from our drinking water. Water treatment plants add chlorine and chloramine to the water to kill any harmful bacteria or other “bad stuff”. One side effect from using a RO Unit is that they will remove some of the “good stuff” along with the “bad stuff”. Because of this you will need to add the “good stuff” (minerals and other essential elements) back into the water befor
