I didn't even know that there was a chloramine test kit. I had problems a long time back and seemed to think that chloramines might be the culprit. First I tried to rule everything out, replaced lots of equipment like pumps in case they were the source of issues. I basically ruled everything else out by a slow and determined process of elimination. When I added a chloramine filter, problems gone. But I'm so paranoid that I replace my sediment, carbon and chloramine filters every three months now. As expensive as that is to replace the filters, it ultimately seemed cheaper than having problems with my sps.
