    Why Single Bed Resins?

    Using single bed resins will give you the ability to use 100% of the resin without having to throw any good resin away. Traditional mixed bed systems are technically exhausted when one of the two charges neutralizes and cannot remove the ions to achieve 0 TDS, even though a portion of the resin may still be usable. Even though using a cation and anion single bed resin will remove a vast majority of TDS it is necessary to use a mixed bed resin after the single bed resins for the best results. 

    Now when it comes to changing your Deionization resins you only need to replace what has been used! Many reefers will find that they either use a majority of the single bed anion or cation resin, but hardly any of the other single bed and mixed bed resins keeping the system very efficient. A little extra money upfront will pay off in the long run with the savings in resin! If the system is maintained correctly the mixed bed resin may never have to be changed.


    All of our RO and DI systems use 1/4" push connect tubing and high-quality Mur-Lok fittings allowing them to be compatible with any BRS RO/DI system and most others on the market today. We only use nuclear grade deionization resin allowing you to create higher quality water with less resin.

    Product Questions

    I received this today and there are no installation instructions included nor can I find anyone or online. Is there a link for how to add this to a BRS 4 stage 75 GPD system?

    Would this work well with 4stage rodi
    Question by: Mike Casey on Jan 26, 2022, 11:10 PM
    Yes, but you will want to re-plumb the 4 stage if you plan to put a carbon filter where the existing DI cartridge is.
