From: Helen Burns Sent: Sunday, April 04, 1999 5:47 AM >Does anyone know the name of the chemical for removing Chloramine... That would be sodium thiosulfate (Na2S2O3*5H2O). It is prepared at 0.1 M in a standard solution, used at 2 drops per gallon. If he has a source or chemist, 0.1 M translates to 25 grams dissolved in water to make 1 liter of solution. -Y- David A.
