I bought some 1000 ppm...4 fl oz bottle.

So I would like to convert it and wanted to make sure my math is correct.

4 fl oz @ 1000 ppm + 40 fl oz distilled water = 44 fl oz @ 100 ppm.

44 fl oz + 22 fl oz distilled water = 66 fl oz @ 50 ppm.

So basically 4 fl oz of CS @ 1000 ppm + 62 fl oz of distilled water should give me 66 fl oz @ 50 ppm ?
