I have an aquafx baracuda 100 gpd system. I have a triple tds meter measuring tds before membrane, after membrane and before di resin, and after di resin/final product. I have the chloramine blaster add on. I need suggestions on how to make sure the chloramine kit is working, or when the filters need changing. I dont know if a freshwater ammonia test will work or a chlorine test kit will work, or if there is a chloramine test. (I couldnt find a chloramine test kit).
