iodine dosing math double check

[dr_vinnie_boombatz]

My recent ICP said I am low on iodine and recommended dosing, is my math correct for a 12.5 gallon tank?

20.01 µg/l
Ideal value: 62.71 µg/l

Add: 42.70 µg/l

converted to ppm
0.02ppm
Ideal value: 0.0627ppm
Addition: 0.0427ppm

RS Iodine+
Liquid supplement: 1ml will raise the Iodine level of 100 liters (25 gal) by 0.03ppm

converted for 12.5g = 0.5 ml will raise by 0.03ppm

therefore need to dose 0.7117mL, or ~14 drops (20 drops to 1mL)

thank you!

I just have to rant, that ideal value for iodine with 4 significant figures is ridiculous.

Math seems fine.

You're welcome.

Happy reefing.
