potassium iodide pills have other ingredients, good for dosing I?

I bought potassium iodide pills and the other ingredients are;

microcrystalline cellulose, dicalcium phosphate, stearic acid, colloidal silicone dioxide, magnesium stearate, croscarmellose sodium.

Should I find a more pure potassium iodide?

yeah, you could get a tiny amount of pure potassium iodide and it would last you a really long time. No need to wonder about whether the amounts of PO4, Si, etc in the pills are reef-relevant.
