Baking Soda and not necessarily remove greenish water. sodium carbonate is used to raise PH and Alkalinity to 7.2-7.6 pH ppm and 80-120 ppm alkalinity.You must use a test kit to find out where your pH is and adjust from there weather you need to go uo using calcium carbonate(baking Soda) or down using hydrachloric or muriatic acid or dry acid.Also you use alkalinity up aka soda ash (sodium bicarbonate) to raise your alkalinity without raising your pH.
