What is RODI Water?
RODI water is reverse osmosis deionized water. It not only goes through reverse osmosis, which removes 90 to 99 percent of the impurities out of the water, but it also goes through the second step of deionization. Deionization is a scientific process that separates ions in order to leave behind only pure H2O, which is undeniably the purest form of water available.
When you add RODI water to saltwater fish tanks, you must mix the salt into the water before it’s placed into the tank.
What is the Difference Between RODI Water and Distilled Water?
Distilled water is water that has been boiled into vapor and condensed back into liquid. It is not advisable to use only distilled water in a fish tank, as it does not have the nutrients fish need to survive. In fact, simply dumping distilled water into an aquarium could harm the livestock.
The main difference between RODI water and distilled water is the purification process. While the RODI process removes ions, distilling water entails boiling it. In both cases, the water needs to be treated with nutrients before it can be placed into a fish tank.
RODI water may also be more cost effective than distilled water.
