Use recommendations 

this product has high content, low impurities and sulfate, routine use of maintenance, such as by 50 kg / barrel chromium anhydride dollars, need to add reagents or analytical pure sulfuric acid 30 ~ 50ml. (This ratio is the amount of chromium added daily maintenance dosage of fluid, the actual test cycle analysis according to the report should also be adjusted).
