I South Florida they use choloramines. TDS read Zero. Many of my corals suffered by either STN or no color.
Bought a choloramine test kit and found the culprit. Added a choloramine filter to my ro/di the change was instant after a few water changes.

A good carbon block filter will break down chlorine and chloramine, but the TDS meter is not intended to measure anything uncharged. The TDS meters are intended to measure how effective the RO membrane and DI resin are functioning. If you want to detect chlorine you need a kit.
On this specific question of whether chlorine is detected, the answer is complicated. Chlorine as pure Cl2 will not be detected by a TDS meter, but in tap water it partly dissociates into other forms, including chloride and OCl-, both of which are readily detected with a TDS meter and are removed by a DI.

Randy- mine ran through Ro/and DI with zero TDS yet when i tested for choloramines it was very evident that it was there.
Yes, I then changed my carbon blocks and it was no longer detected, but the fact that it was there after ro/di has made me very paranoid.

AquamanE...can I ask where you purchased the chloramine test kit. I've been unsuccessful in my search. Found plenty of chlorine tests.

Fwiw, any chlorine kit will detect chloramine. You only need a chloramine kit if you wan to distinguish it from ordinary chlorine. I use and like the Hach chloramine kit.

FWIW, I was only referring to chlorine, not chloramine,which does not dissociate the same way into charged species.
