## Overview

TL Reefs Deionization DI Resin is a premium mixed bed resin designed for the final purification stage in RO/DI systems. Featuring a unique color-changing indicator that shifts from purple to amber when exhausted, it provides a clear visual cue for timely replacement. Each 1.25lb vacuum-sealed packet perfectly fits a standard 10" DI cartridge, ensuring maximum shelf life and optimal ion removal for zero TDS water.

## Description

DI Resin is used as a final stage in an RO/DI system to fully remove all ions and provide zero TDS water. Our DI Resin is a premium grade, gel type, high capacity, color indication mixed ion exchange resin prepared with a 1:1 chemically equivalent ratio of cation to anion resin. It is specially manufactured with a color indicator to visually show when the resin is exhausted and requires replacement. The beads will turn from a purple color to a light brown, or amber when exhausted. A big concern with the giant bags of DI resin that you can purchase at discounted rates, is that once it is opened and exposed to air, it begins depleting. Our DI resin is vacuum sealed in single-use mylar bags to prevent any air intrusion. To maximize efficiency and shelf life, we only supply single use packets. Each packet is enough to fill one standard 10" refillable cartridge.

## Features

- Color Changing DI Resin, changes from purple to light brown/amber color when exhausted
- Each pack contains enough resin to fill 1 standard 10" DI Cartridge
- Individually packed, vacuum sealed for maximum shelf life

    Perfect for Reef Aquaria
  

*by R***9 on Reviewed in the United States on February 3, 2020*

One has to understand what the actual TDS reading of their local tap water before judging this product.I recently changed all five (5) stages of my RO/DI filtration unit. Sediment, Carbon Block, RO, DI, and post Carbon filter today (Feb 2, 2020).TDS reading after two (3) stages (Sefiment, Carbon Block filters and RO unit): ‘8’.TDS reading after going through the fourth stage  (DI resin): ‘0’.•Photos I’ve attached for reference.The longevity of the color changing DI resin is dependent on the local water supply and the filtration it passes through, in my case ‘newly’ changed filter media (all five stages of them).DI resin, in the long run, would be less costly to replace when used the proper way.I’ve done 20Gal as of the moment for sea salt mixing and still the DI resin hasn’t changed a bit (usually changes from the bottom of the cartridge).Now, I’ve tried BRS’ and Marine Depot’s color changeing DI resin and seemed to notice instant color change after just 10Gal of freshly filtered water. I would not judge their DI resin too quickly since I’ve been running the rest of the filters (Sediment, Carbon Block, RO unit, besides the post Carbon Block) for a few months since.I’ll be ordering TL Reef’s brand starting today for my DI resin replacement.Update: (February 4, 2020), after 40gals had passed readings on my TDS (product water): still at ‘0’.Post RO TDS reading still at ‘8’.Apparently no significant change.Update: (February 10, 2020), 60gals mark, DI resin had a slight color-change. Post DI reading for TDS, surprisingly still is ‘0’.Update: (February 13, 2020), 100gal mark, DI resin obviously had significantly changed color. Close to changing it when it reads ‘5’ on the TDS meter. As of now post DI reading still at ‘0’ TDS.👌🏻Update: (February 18, 2020) I recently purchased another bag of the product expecting previous load would have been exhausted by now. Already had filtered 140gals and yet, TDS, post DI is still at ‘0’.I’ll just have to wait till the next reload.Update: (February 24, 2020) I’m very amazed that after filtering 160gals TDS is still at ‘0’. Key is to have a well maintained prefilters such as sediment filter, carbon block, RO filter prior to the DI stage, I do however have a post carbon filter after all the 4 stages. Also, planning to expand to 6 stage by adding another carbon block as the 2nd stage. Already did receive my 2nd bag of DI from TL Reefs but didn’t see a reason why I should be opening it besides, I still probably have a cup left from the first bag that is unused. This product with all the filtration stages will save you a lot of money. I did have to replace the 10” DI refillable every week but, with the new set of filter media the DI resin doesn’t have to work that hard. I also have installed a constrictor (rated 50gal/hr) on the waste water side of the RO shell. All working great!👌🏻Thank you TL Reefs!!!Update: (May 12, 2020) it’s been months and several hundreds of gallons later, color has changed on the DI resin. Still the TDS on the ‘out’ reads ‘0’. I guess I’ll just have to wait until it reads ‘2-3‘. It’s been a very reliable brand⭐️⭐️⭐️⭐️⭐️*Color change picture posted

    Works great and easy to use
  

*by F***R on Reviewed in the United States on October 22, 2019*

Used on an R.O. filter system to collect tap water for water changes on saltwater aquarium and for drinking water. In the past I bought the entire canister didn't know a refill was available.  So now saving a bunch of money.  I noticed my 'zero water' meter was no longer measuring zero so knew it was time to replace D.O. filter.  It was easy to replace the media.  Used a funnel to keep from making a mess.  More than enough to fill my canister.

*by K***L on Reviewed in the United States on July 18, 2018*

This is just over the amount needed to tightly pack a DI cartridge. Working well so far, 0 TDS water. I guess time will tell if it exhausts too quickly, but so far no complaints
