Chloramine

I currently have a whole house sediment filter followed by KDF-55 & GAC filter and a water softener. I recently took a sample of my tap water to the LPS to test for chlorine, there was no chlorine in the water. Does this mean that there is also no chloramine in the water? My water district uses chloramine to treat the water.
 
I really don't know, but a bottle of Amquel is really cheap in the whole scheme of things. If worst comes to worst, dose this stuff... It works for me and I've been using tap water for a LONG time now.
 
I have a 50gpd RO unit that I use for drinking water, my plan is to tee off of that and pass it through a DI. My concern is if I need anything else to ensure there is no chloramine in the water.

To tell you the truth I'm not too familiar with these RO/DI units out there, but I have heard that there might be "another chamber" so to say to eliminate Chloramines if that's the case. I wish I had more information for you, but I'm sure somebody else will be happy to help you out here soon. Good luck!
 
I think, no clorine, that means also no cloramine. But no sure the test of your LFS is the low range.

Your filter (KDF 55) can treat clorine but you have to check to know that how long it's filled to exchange the media.

If you use for your tank, you also have to treat TDS (Total Dissolved Solids) in your tap water.

Hope these help

You'd be better of buying a dedicated ro/di for your system and running a chloramine filter for good measure.

Good plan, the RO can treat clorine. I never test it, just test TDS regularly.

Due to lazy, I double TDS stage :)

Personally I would invest in a set of specialty carbon filters that are meant to treat chloramines. Buck Eye Hydro and Bulk Reef Supply are vendors here that carry them.

Your normal carbon filter can treat chlorine, but Chloramines are a combination of Ammonia and Chlorine. You will blow through a regular carbon filter in no time flat. Chloramines need a bigger carbon filter and more contact time.

What you need is "catalytic" carbon which is meant to treat chloramines. Just spend the extra $$ and get the better filter, instead of guessing if your regular carbon filter will have enough contact time to treat the Chloramines.

You can get regular carbon block filters for your ro/di that remove chloramine in addition to the specialty ones. Spectrapure's .5 micron carbon blocks remove chloramine.
 
BRS has a carbon block specifically made for chloramines. Their normal carbon blocks will get chloramine breakthrough in no time. I believe BRS has several videos on this subject and they did test different carbon blocks to treat for chloramines.
 
Chloramine is almost always accompanied by some free chlorine. Did the lab test for FREE chlorine, or for TOTAL chlorine?

I think they only tested for total chlorine. I will be getting my own test kits before I set up my tank. Which test kits would you recommend?
