Quick Overview

This kit works with the BRS 5 Stage RO/DI System, BRS 5 Stage PLUS RO/DI System, BRS 5 Stage Water Saver PLUS. This kit includes:

  • Purtrex 5 Micron Sediment Filter

  • MATRIKX CTO 5 Micron Carbon Block

  • MATRIKX CTO 0.6 Micron Carbon Block

  • 1.25 lb. Color Changing DI Resin Refill

We recommend changing sediment filters when they become visually dirty or there is a noticeable drop in pressure. Change carbon blocks every 6-12 months depending on use. This kit does not include a membrane filter as they need replacement every three years or so, depending on water and set up.

  • Rick Needs to Learn How to Read By Paul on 1/29/2015

    "This kit does not include a membrane filter as they need replacement every three years or so, depending on water and set up."

    If you read to the end of the listing, you will see that it does not include the membrane filter. Why is that? Well, the membrane filter needs to be replace every 3 years or so. The other filters are replaced much more frequently . . . every 6-12 months. I've been using a RO/DI filter for approximately 2+ years and have used this particular replacement kit each time. It worked great when I had a 150 gallon saltwater tank. I've gotten out of saltwater and am now using RO/DI water in my Cichlid tank. This replacement kit has worked well for my needs.

    Everything you need right there!!!
  • Everything You Need By Ryan on 11/13/2014

    This Replacement Filter Kit for my RO/DI system was everything I needed, and we've ordered it every single time when replacement was due. The kit shipped quickly, and was easy to understand and use. The how-to video's verified that we replaced everything correctly and with the DI Resin having a little extra, we were a little nervous that we did something incorrectly. BRS confirmed we did everything correctly, and a little excess was okay. Again, the BRS recommended replacement kit was much easier than ordering each piece separately!!

  • great for replacing my rodi filters By Kevin on 8/23/2014

    it came with perfect instructions very simple to switch out filters but
    i'm giving this filter replacement 4 stars because i believe it should come with the di resin sponges. if you read this i suggest you buy the replacement di sponges or maybe bulk reef should add them to this package.
  • Simple & Fast By Nicholas on 5/30/2014

    My system was not used for a long time and I thought it would be best to change everything out. BRS has made it really easy to buy these rather than searching the web for each part separately. Really simple and ready to use. Videos from the site helped a lot.
  • Great Package! By Stephane on 5/27/2014

    everything is packages to make it easy. as a new reefer all i had to do is look up this kit and order. After, the install was done because BRS labels the filters. i just matched the labels to the canisters.

    I can say that you can see the quality in these filters, they are not built cheap.... proof is when my meter still shows no TDS.
  • Great Filters / Great Buy By Jeff on 5/10/2014

    Yes these are Great filters at a Great price but no matter what you order or no matter how much it weighs the palin old ground delivery cost a fortune and Always takes a week and a half to two weeks to get to Florida. It seems that those whos orders are under $175.00 are paying for the free shipping of the others.

    Saying that...I have ordered supplies from these people for several years now, they have good quality stuff, just wait till you need $175.00 worth and don't be in a hurry.

  • Good Filters By John on 4/1/2014

    Mine last quite some time. Its time for a refill now. Will be going with the same parts. Fast shipping.
