One milligram( not 1 ml) of any substance in a litre is 1ppm so to get the figure you desire multiply the concentration you need by the volume you need.
30 x 200 = 6000mg so you need 6 grams of 100% sodium hypochlorite, since sodium hypochlorite is normally supplied in a strong solution you would need to add more than 6 grams of that solution depending on its concentration and density.

parts per million (ppm) = mg/L or 1 : 1000,000
5 ppm of NaOCl = 5 mg/L solution
Since NaOCl powder is generally unstable at room temperature, so it is available in the form of solution.
Household bleach is, in general, a solution containing 3–8% sodium hypochlorite (m/v).
Assuming that we use 5% NaClO (m/v) = 5 g/100mL solution or 5,000 mg/100mL solution or 5,000 mg x 1000mL/100mL = 50,000 mg/L solution.
So, to make a 5 ppm of NaOCl solution, then measure out (5 mg/50,000 mg) x 1000mL = 0.1mL of 5% NaClO.
Pipette out 0.1 mL of 5% NaClO, transfer it to a 1000-mL flask, add some water to mix, then add more water to the mark.
