RO/DI unit with or without chloramines filter?

[M.phenax]

I've finally decided it is time to stop hauling water home from the LFS but now, I can't figure out which rd/di system to buy.:confused:
BRS has regular systems and systems that remove chloramines. Is it really necessary to have the chloramine unit? For those who have regular ro/di systems, do you use Prime to remove chloramines, or do you not have chloramines in your tap water?

Just ring BRS and ask them and Contact your local water department and ask them if the water has chlormines in it.

Our water does contain chloramines, and I am looking to buy a unit that removes them. However, I would like to know what kinds of systems other people have and how they address chloramine removal before I drop cash on something I don't really need.

A high quality carbon block will remove chloramines. Two may be necessary in some situations. A cheap chlorine test from pool supply stores can verify that they have all been removed. I have a 5 stage unit so it has two carbon blocks. I have never had any chloramines get through. I do change the carbon filters every six months whether or not the pressure dictates them needing replaced to be on the safe side.

Thanks for your input! Which rodi systems are you using?

I've always been told it 20" of carbon to remove chloramines. I.E. 2 standard 10" carbon filter blocks.

+1 on checking your water and then making purchase. My water does not have any noticeable amount and after my 5 stage it comes out nice and clean with no traces of it but this varies from each persons water source.

I also think It depends on the blocks.. Spectrapure rep told me that it is not needed with the maxcap 90 that I have due to the high quality carbon and small micron size.. I haven't noticed any negatives not using a special filter but I also change them out religiously at 6 months. I also had a 5 stage before this one that worked just as well. I have really low TDS water though 40ppm is the bad time and 15ppm is the norm don't know if that really matters how much it is treated with though .

1. Call or lookup the details about your local water.
2. Pick a 4 or 5 stage that handles Chlorine or Chloramine (handles both).
3. I use the BRS Chloramine 5 stage and it works great, call them or another Reef Central sponsor dealer (hear fire and ice is great too).

You will be happy with the unit.:bounce3:

Just keep in mind that the 5 stage unit I have takes about 20-23 minutes to make a gallon of RO/DI water.

Enjoy

Quality units will handle chloramine without the extra cartridge..
