HELP! Dealing with Chloramine in tap water?

[marcelft]

So I just figured out there is chloramine added to my tap water, so my RO/DI water is full of ammonia. Anyone deal with this problem??

The DI will remove the ammonia, if properly functioning. I have a similar issue and all is fine.

I discuss it here:

and

Using RO/DI you shouldn't have anything at the end. If your filters and resin are good all the chloramine should be removed. Your area is notorious for poor water quality. You must remove the NH2Cl from the tap water because it is toxic to fish. Aging the water for a few days removes chlorine but not the more stable chloramine.

The Filter Guys supposedly have a filter that takes Chloramine out...Im checking into it, does anyone have experence with their filters, or chloramine filters in general???

Most normal (good quality) RO/DI systems do it just fine, and there is no need for extraordinary filter, IME. It is easy to measure the effectiveness with an inexpensive chlorine kit if you want to. :)

Any good quality RO/DI with high quality filters will remove chloramines. You do not need extras like catalytic carbon for chloramines ate normal drinking water levels. Vertical high capacity DI filters with good contact time work better than low capacity horizontal DI housings though. If you have a horizontal on top of the RO membrane, remove it and mount it vertically next to the unit so it fills from the bottom and exits the top for better filtration and make sure it is packed tightly, no empty space.
