I recently purchased a Chloraguard carbon block and want to know if it needs to be placed before or after my chlorine grabber carbon block.

After doing some reading, I have seen advice both ways. Every chloramine reducing R/O system I have seen offered by different vendors contain both, but doesn't the chloramine block remove chlorine as well? What is the purpose of using both?

Thanks

I'd go in this order:
sediment filter(s)->Chloraguard->other high quality carbon block

Chloramines are more difficult to remove than chlorine, as chloramine requires more contact time with the carbon. 2 carbon blocks = double the contact time. The Chloraguard is made a a special very fast acting type of carbon. Yes - it will "remove" both chloramine and chlorine

How do I know when it's time to change out my chloroguard and carbon blocks?

Those filters are the best on the market - they are rated for chloramine reduction at 3,500 gallons @ 0.5 gpm capacity. Like any carbon block, I'd replace it at about 1/2 to 2/3rds of the rated capacity.

You can also test for chloramines if you'd like a more precise answer.

Not to thread hijack but how do you test for chloramines? The same as chlorine?

You can test for chloramines by measuring Total chlorine, and also free chlorine, Test kits for each are available at buckeye, and are widely available elsewhere too.
