Today on BRStv, we have a brand new episode of our series, BRStv Investigates. In this series, we explore popular reefing theories, products, methods, and what the manuals are missing, with a focus on putting them to the test!
In this week's episode, we take a look at deionization resin and how to make the resins work better and more efficient.
There are a few different types of DI resin available these days from single bed anion to mixed bed cation resins and each of them have a different purpose. A majority of resins are color changing and will have a pH reactive dye on the resin to let you know when it is exhausted, but it is still best to use a TDS or EC meter to know exactly when contaminants are coming out of the resin. Now, the color changing indicator can be on either the cation (+) or the anion (-) resin and when the pH of the resin becomes lower than the threshold for that particular media the color will change to a light amber color as the pH of the resin becomes neutral.
If you have a silicate, phosphate, calcium, CO2, or any other issue with your RO water, their ware ways to modify your current DI system to become more effective and efficient, it more than likely just takes a different type of resin.
So you want to learn more about DI resin? Make sure to watch the video, as we will give a few tips to create the best water possible without throwing away good resin!
