should I worry about chloramines from RODI

[moz71]

So i just read something that peaked my interest and not sure I should worry. I have an RODI unit with all new filters and one is the "special" upgraded one to help remove Chloramine water test 0 TDS. However I just read TDS does not pick up Chloramines. Question does anybody still put in Prime (chlorine remover)? Just assume it is removed? test for it? Not sure if i should be doing something else

You Should not be worried, most rodi unit (at least 4 stages ) will filter low volume Chloramine

thank you, worried because I know my town adds a good amount of Chloramines to our water! Phew!

It’s won’t be a terrible idea to get an ice test done or get a report from local municipality around on the water chemistry , that will address any doubts and also a good long term strategy , as water chemistry is the most important aspect and knowing if there’s any other metal or anything else (silica, arsenic etc ) would be good. If you know there are already other reefers from that area that’s a good base line as well

It is easy to remove chloramine from your water. If you store your RODi water in cans or buckets – just ad around a coffee spoon of vitamin C (ascorbic acid) to each 20 litres.

A better bet would be to actually get some test strips and check from time to time. They don't cost very much.

If your water supplier puts a good amount chloramine in the water you should be concerned and should remove it prior to it getting into your RO membrane. While treating the water post filter will remove the chloramine, it does damage to your RO filer membrane on the way through and will reduce its useful life. I had a heck of a time with STN over a year period until I figured out chloramine was the issue. I added a BRS chloramines monster carbon filter ahead of the RO system and that solved my issues within two months. BRS has a good video on chloramines and carbon blocks.

I do have one of those monster carbon filters before the membrane. Since not sure how long they last I will test periodically to be on the safe side. Although I DO NOT want any more testing than what is already required I will test this once in awhile My wife thinks I am some kind of crazy chemist with all my test kits. CRAZY but we love it

You're good then. (Yet still a crazy chemist)

I go through alot of makeup water and change my monster out once a year. Its too hard to accurately monitor how much water I filter but at a 20,000 gal rating for the monster, I'm comfortable that once a year is plenty frequent enough. I don't even do chlorine tests anymore.

My BRS Monster is over a year old and still working great. My Levels are higher from my water coop, than what I keep my pool at.

Thanks all. Good info to know. Made me feel more comfortable.

First question is whether you even have to worry about chloramines. Your city should have a report on water quality and list what they add. If not you can call the public works department and ask.

I did read report about it. Specifically states they put Chloramine in water AND specifically said ok for humans but can affect aquariums. Couldn’t be more direct. Lol

I would not be concerned if you use a decent ro/di, but any cheap chlorine kit is fine to check the effluent. It need not be a chloramine kit.
