  • 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.
  • DI By Rich on 3/31/2014

    A great purchase well constructed can be installed in minutes and really removes TDS a must have for the water quality you need in the tank
  • perfect! By matt on 3/5/2014

    After my RO unit it was still at 70 TDS. This unit pulled it down to 0 and has made over 100 gallons so far keeping my fish and coral very happy!
  • Works Great. By Red7Xero on 1/21/2014

    My old DI resin was 1 year old and still had an output of 0ppm, I decided to change it out with my carbon and sediment filters. And because I wanted to add another carbon to the mix, I bought this to add another stage and with it including the DI made it an easy purchase.
    After installing the sediment, 2 carbons, and the new DI units, taking around 10mins, thanks to BRS TV series, it worked like a charm.
    Thanks again BRS.
  • update on earlier review By Aquaticfan on 1/7/2014

    I am sad to report that the system can not handle the high TDS still coming from my existing Water softener system. I thought it could but after a 5 gallon fill, the TDS is rising. I will have to get an RO system to connect it too. I still love the product though.
