I've been working on reducing my nitrates on a new tank and I started inquiring with my water company about what their using. I'm in Monmouth County btw. They currently are treating water with chlorine but they will start in April using chloramines again. I wanted to pass along this info for the folks who have home RO/DI systems in place for water changes and makeup water.
If your water company is NJ American water read this

Good info to share. I received a letter from Freehold Township last year that they were switching to Chloramines. I checked with AWI and they confirmed that their RO/DI was more then capable of removing them.

When did they stop? I received a letter about 18 months ago stating a switch over to Chloramines permanently, due to the stability of the chemical for a long period of time. Regardless, I have added a DIY Catalytic carbon filter before the RO membrane and I don't plan on ever removing it.
My next one is bone char, but I have to figure out how much fluoride is getting the RO.
What RO membrane do you have that Chloramines won't pass the membrane? I remember reading something about the Dow Filmtec membranes don't block chloramines, so I added the catalytic carbon.

Not sure when they stopped but in the Monmouth county water sources they did release news a while back that they moved to free chlorine in the winter. I called and spoke with a specialist. I'll have to go and look at what my RO membrane is but I'm pretty sure it takes a chemical reaction to break the chloramine compound to something else. A lot of chemists on the forum argue that the RO/DI won't remove chloramines. I'll be putting some thing bigger in the filter system post sediment and carbon before the RO as I topoff directly.

I have the AWI Typhoon III extreme and they said its more than enough to take care of it. I also keep a 29g tank filled with RO/DI that I draw off of for top off so the water is sitting there letting the chloromines bleed off. Haven't had any issues that I can attribute to it and always show 0 TDS. Will chloromines show up on a TDS meter?

Lostinthedark - from my readings, and I am not a Randy type chemist, but, the issues with chlorine and chloramines is, when the water sits, Chlorine will dissipate either through aeration or wait about 24 hours of sitting. However, Chloramines can remain in the water for a much longer period of time due to its stability. If memory serves, 7 days, if not 14 days. I want to say 14, but, I can'

Chloramine does not dissipate easily compared to chlorine.
Chloramine stays in the water distribution system longer than chlorine.
Chloramine is difficult to remove.
Chloramine cannot be removed by boiling, distilling, or by standing uncovered.
From the water companies perspective : Water sits in the pipe for a few days and bacteria can start to grow due to the chlorine dissipating. While the chloramine module will remain in the water actively working to keep the water bacteria free for a much much longer period of time. I am not sure of the health issue to our bodies, but fish don't tolerate the chlorimine very well. Is it not deadly, but not beneficial to them.

Seachem prime still neutralizes chloramines I hope

Looks like Seachem prime does have a benefit regarding the "dreaded" chloramine.

This is what I'll be ordering from filter direct which is where I get all my RO filters etc. https://filterdirect.com/product_info.php?cPath=25_76&products_id=286
