If you already have the chloramines system you would be better served by the existing filters which are more effective and less expensive. The two chlorplus block concept would is meant to be an option for folks who don't have a carbon rinse valve that simplifies the rinsing of the catalytic carbon.
You would want both. The catalytic carbon is actually the filter that does the majority of the chloramine removal when they are paired up.
Chloramines are different that chlorine which is used by most municipalities to treat the city water supply. Chloramines are chlorine reacted with ammonia to create a more stable disinfectant. At least 10% of the nation’s water supplies now treat their water with chloramines.
To find out if your city is one of them, call your city water supply and ask them directly or ask for a water quality report. To find the number for your water treatment facility check your water bill or call city hall.
Recommended filter arrangement for chloramine treatment when using the Chlorplus Carbon Blocks
- Stage One - Sediment filter
- Stage Two - Refillable cartridge with Catalytic Activated Carbon -
- Stage Three - Pentek ChlorPlus carbon block
Note: With advancements made in filter technology we now supply BRS Universal Carbon Blocks and include them on all of our BRS Universal RODI Systems which we would recommend for chloramine filtration over the ChlorPlus Carbon Blocks. If you wish to upgrade your current system to utilize BRS Universal Blocks you can easily change out the catalyic carbon, and ChlorPlus filters for Universal filters.
Great product By Mack1969 on 5/17/2017Mack1969 would recommend this product to a friendIt's diffently decrease my resin use.
No real difference By DurocShark on 11/17/2015DurocShark wouldn't recommend this product to a friendI replaced the OEM block in my filter with one of these. Without the DI resin, I could still taste chlorine at the same level as the original carbon filter. Granted, I'm in SoCal with lots of chlorine and chloramine, but I was hoping for more.
Now, having run 100 or so gallons of produced water, I'm burning through DI at about the same rate. At least in my environment, it wasn't worth the price premium.
Informative Video on Choramines By Bill on 3/8/2015Bill would recommend this product to a friendGreat video on how Chloramine's are not removed from my 4 stage RO/DI. 5th stage was easy to hook up. CS was helpful on what was needed.
yes, but use it with catalytic carbon By Charles on 2/28/2015Charles would recommend this product to a friendThis works well, but I suggest using it with activated catalytic carbon. Really removes the chloramines.
Very Happy By Randy on 1/6/2015Randy would recommend this product to a friendI purchased an RODI system and it came with regular carbon filters. Well I didn't know very much about this, but my system went to the fishes in about 2 months with only 300 Gallons used, and TDS was running at around 26. I then did more research and found out my area uses Chloramines, and it pretty much killed all the filters I had on my system. I then repurchased all filters from BRS and everything is working like a charm. These filters did the job and hope that it last me more than a few months this time around!
You need this if you have Chloramines in your water By Chad on 3/4/2014Chad would recommend this product to a friendI've been using these for years and love that BRS carries them. Alot of water companies are using Chloramines now, and if they are, you need to be removing it from your water. This is as good as it gets for removal as far as i'm concerned.
Highl Recommend Adding ChlorPlus 10 Carbon Block By Kenneth on 2/17/2013Kenneth would recommend this product to a friendA number of cities are starting to use Chloramine. Chloramine is becoming more common as an alternative to chlorine for water treatment and must be treated differently. Your ciity can switch over without leting you know. Chloramine left untreated can cause alge blooms in your tanks.
A must have! By Jesse on 4/25/2012Jesse would recommend this product to a friendI started making my own water about a year ago and since have had some algea issues. I've tried everything under the sun to correct it. Then I started researching Chloramines (after seeing a BRS video on it) and the affect it has on a reef tank. Thinking this might be my problem I called my county water supply and sure enough they use Chloramines in our water. I added this as an additional stage to my already 4 stage RO/DI unit (which made it a 5 stage now). I have already noticed that I don't get the algae breakout after top offs. So with time I hope this will rid my algae problem. Thanks Bulk Reef you opened my eyes to Chloramines.
No more dechlorination and dead fish By Michel on 11/30/2011Michel would recommend this product to a friendThat was a great investment and if my fish could talk, they would probably thanks me!!!
it's expensive so I put 4 stars as value
It works By Brian on 9/20/2011Brian would recommend this product to a friendChloramines are a persistent disinfectant ... the last thing I want in a reef system. The City of Houston endeavors to provide safe, high-quality drinking water and uses Chloramines to sanitize surface water and keep it safe as it transits the over 100 year old delivery system. For me, a Chloramine filter is a slam dunk.
Great deal and great performance. By Alexey on 10/1/2010Alexey would recommend this product to a friendAfter completely tearing apart my regular RO system, I replaced the cheapo carbon filter with this guy. It cleans up chloramines which are being added to water in more and more municipalities, it's bad stuff!
The price here was pretty good for this unit and I haven't regretted my decision. I also added a regular carbon block filter right in front of it as well. It's got a really good mesh to prevent any carbon seepage which can really affect the life of your RO membrane. Good stuff!
