Hi every one is telling me i should run a dual di. Set up my ? Is what will i benafit from adding another di. To my system if im allready at 0ppm tds no one has been able to tell me. Thanks in advance for the advice
Question by: Nathan on Feb 27, 2014 5:16:00 PM
Hi Nathan,
Running a dual DI will not make your water any cleaner as a single DI will bring it down to 0 TDS. What the second DI chamber does is allow you to get a bit more out of your DI resin.

For example, if you have 5 tds going into your DI resin you should have 0 coming out. When that goes up to 1, its time to change your DI resin out even though technically its not fully exhausted (its still removing 4 of the 5 TDS). A dual DI allows you to fully exhaust that resin and the second DI filters out the 1-5 TDS that gets through. That way your still putting 0 TDS in the tank while fully exhausting your first cartridge.

Does this come with the color changing DI resin or normal resin?
Question by: Kelly on Oct 19, 2013 11:46:00 AM
Hey Kelly,
All of our DI's come with the color changing resin.

Is it normal for the canister to be filled with air instead of water once up and running?
Question by: Matt on Jan 27, 2014 11:52:00 AM
Hi Matt,
Perfectly normal and the way it should be. DI canisters work on an upflow principle compared to the radial flow of the other filters so the air is just a bubble that can't escape, nothing to worry about!

At which point do i add the DI to my existing RO filters. Is it after the membrain, or after the third canister?
Question by: Brian on Jan 31, 2014 9:03:00 AM
Hi Brian,
A DI resin filter would be the last filter in the set, so after the membrane the last stop before your water goes to your storage container.

  • Single Deionization Canister By chuck on 9/10/2015

    I really like it! I now have 1 canister to fill, rather than the 2 smaller ones I had before. It came filled with the deionization resin, that was very nice. Thanks BRS
  • Perfect By Joshua on 7/22/2015

    love having the second canister on my 4 stage as then when first is exhausted i can simply switch the 2nd one to the first location and refill the canister that was in the first spot and put in the second one that way im fully using up all di resin and getting more life out of it...far better than i was expecting on life of resin after i added 2nd canister
  • Works Perfect By Mike on 7/13/2015

    I already have a reverse osmosis filter for my drinking water and needed the RO add on for my aquarium. Very easy to install and works perfect. After 200 gallons I am still getting 000 on my TDS meter. Just make sure to get the cap really tight or it will leak a little.
  • Perfect By Joshua on 7/10/2015

    added this to a 4 stage made 5 stage with an add on prefilter to make it 5 stage and add this to make it a 6 stage as i was trying to lower tds into the di as i was burning through resin too fast reason i added the other prefilter which gave me 2 carbon blocks and with the 2nd di chamber makes everything easier as since you dont fully use all of the di resin before you start producing 1 tds with the 2nd chamber you can fully exhaust the first chamber/canister before changing then when i refil i just swap out the 2nd chamber and move it to the first location to use the rest of that canister and add the new canister to the 2nd location
  • Well worth it By Lee on 7/9/2015

    This is my second DI unit. I wanted the flexibility to not worry about whether the first cartridge is completely used up before replacing it. Now, when the second in line starts to change color, I switch them and refill the original placing it in the second position.
  • Nice Unit By Eagle1 on 6/28/2015

    Hooked up this unit and found my DTS to be zero, well built , easy to install
  • Very Nice Product By Eagle1 on 6/11/2015

    I just installed this unit on another RO unit, 120 going in 0 coming out, seems to work pretty good, only time will tell but I am pleased with the unit so far.
  • Good product, comes with everything you need By tjacob105 on 5/23/2015

    Running nicely on my 5 stage. Burns through di pretty quick though
  • Works great! By LMDetail on 5/22/2015

    This works great for my water scrubber! Have already ordered 3 more!
  • great product By carcrazy072405 on 5/15/2015

    Great product works as described
  • great product By o2c5 on 4/26/2015

    I am glad someone has thought of a way to quickly look to see if the di resin has become exhausted. love this
  • Great DI Canister By Jeff on 3/18/2015

    Added this to my existing RO unit along with the 3-way ball valve to direct water to our drinking water storage tank or to the DI. Highly recommended!
