RO/DI for Chloramine

[feeeesh]

Hi everyone- could really use some
Advice. I would like to purchase a
RO/DI system and trying to find something ideally at about $150, could afford a bit more. The one catch is that I would like for it to remove chloramine as my water district treats our water with it. I understand few systems do this off the shelf and i may need to upgrade to get this capability. Really hoping someone can provide excellent guidance. I have a 75 gallon so water changes are about 10-15 gallons on the weekend plus about 1-2 gallons top off during the week

BRS 5 Stage RO/DI system will remove chlormines. https://www.bulkreefsupply.com/5-stage-premium-plus-75-gpd-ro-di-system-bulk-reef-supply-bundle.html

My city also has chlorine/chloramines and I opted for the 6 stage, just to be extra safe (plus based on my city's water quality report, it seems like they use it often.)

My city also uses chloramine, so I’ve got the BRS 6-stage RODI. Works perfectly. My system is 90 gallons and I use it for all my water. I confirm chloramine removal regularly with dipsticks, and I also had ICP analysis done just to be sure. All chlorine and chloramine is removed with this system.

Chloramine removal usually involves 2 carbon blocks (1 regular followed by another designed for chloramine). This can be added pretty easily with one extra filter housing and some tubing to connect it to the system.

Thank you Gedxin, Spieg, and Bad Squishy. I have attached the chloramine info from my
City. Does this appear to be a lot?

My city uses the same amount as yours. Looks pretty typical.

If you install 1 micron or less carbon filter you will not need an extra stage for chloromines. Not many people know this because it's buried deep in the abyss of research. When you buy most of the sets at BRS, etc, you get 5 microns. They are just okay. I always use 1 micron or less (.5 if you can) for both carbon and sediment. This way, your latter stages will last much longer.

If I was you I would buy both of these RODI systems from this guy. https://www.reef2reef.com/threads/ro-di.857432/ Take the 4 stage filter, replumb it into sediment, carbon, carbon, and then a chloramine carbon. Take the two RO housings plumbed in series to make a 200 GPD output, the take those last three housing to use as the DI's.

With such a small amount needed a 50 GPD unit would suffice.
Try Spectrapure or Buckeye Field Supply. Both are reputable companies.

If that much water isn't needed, one could always just put in dual 50gpd membranes instead. But the point was for $110 he could make a top notch system. IMO it doesn't matter who makes the housings (they probably all come from the same Chinese factory anyway) as long as they hold standard filters. Then just buy high quality filters for it.

Try Buckeye Field Supply.

Thanks for the plug! We changed the company name to Buckeye Hydro about 15 years ago.

Have a read through this, by Randy Holmes-Farley. It should provide some helpful information for you.
It actually helped me decide on what kind of system to buy for my house, because my local supply uses chloramines too.
