    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

    Bulk Reef Supply 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.

    Is it normal for the canister to be filled with air instead of water once up and running?

    Bulk Reef Supply 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!

    Does this come with the color changing DI resin or normal resin?

    Bulk Reef Supply Hey Kelly,
    All of our DI's come with the color changing resin.

    At which point do i add the DI to my existing RO filters. Is it after the membrain, or after the third canister?

    Bulk Reef Supply 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.

  • 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!
  • Works as advertised By Bryan on 3/11/2015

    I added the canister to an existing RO system. It took my TDS from 44 PPM to 0 PPM. Excellent build quality.
  • Single Deionization Canister By Shawn on 1/23/2015

    Very simple to install and works perfectly. Immediately took everything to O TDS. It's a definite must have!
  • Quality By Kemly on 1/11/2015

    Product was quality and at reasonable price.
  • pretty good results By astr on 12/24/2014

    Added this to a 5 stage ro and have tds at 5 on the first fill.. Could be from the container i was using though. I love not having to transport water now!
  • No down side By Frag Shark on 12/16/2014

    This is a simple effective upgrade for an RO system. It extends the life of your DI resin by allowing the first DI to be completely depleted before being replaced. It is also an easy way to add a DI stage to a RO unite that doesn't have one.
  • Great way to get TDS to 0 By Nanoman28g on 12/11/2014

    I had been using a three stage RO unit for years with a TDS reading of 10, but most people say that is not ideal for reef tanks, so I went ahead and installed this DI unit, which brought my TDS down to 0. Great product and very easy to install.
  • It's great! By Steve on 12/7/2014

    I had a BRS 5 stage system already, but added this canister to get the most from my DI resin. Even when the resin has changed color, it still has a little bit of life in it, so this way I can stretch my DI dollars a little bit. It's identical to the canisters I already have and as an added bonus - it came already full of resin! Bonus!
  • good deal By chillermike on 11/15/2014

    I purchased this because I wanted to get the most out of my resin. I added it to my existing 5 stage system. When the 1st di changes all the way to brown the second one is picking up the slack. At that point simply change the cartilage and add new resin to the depleted one. No waste I get the most out of the resin for a 40.00 dollar investment and by the way you get 13.00 dollars worth or resin with the canister kind of a no brainer you are only paying 26.00 for the canister such a great deal.
  • Easy to install By Bob on 11/9/2014

    Easy to install. This 2nd unit will prevent producing TDS water greater than 0 for my reef tank when the first unit is exhausted.
  • A must have for your R.O. unit. By Michael on 9/2/2014

    Instantly solved my TDS problem. I had been struggling with TDS readings from 3-10 for several months. New filters did not solve my problem. I installed the BRS DI Canister and my TDS went to zero. As usual with BRS, the item was top quality and shipping was fast.
  • Works great! By Van on 6/1/2014

    I have an RO filtration system at home for drinking water. It's a great system but not good enough for tank water IMO so I decided to add this canister. Installation was a breeze - I tee'd off the final output of the RO system to this DI canister and so far, it works great! TDS went from 15-20 to a solid 0 and has remained this for months now. Very happy with it and my fish/corals are having a blast as well.
