Can iodide be used as a dip or do I need to get lugol's?

Lugol's is 5% iodine and 10% potassium iodide. Directions are specific in being very careful with dosage.

Iodide is less than 1% potassium iodide, no iodine.

So... even worth it?

Nothings 'wrong' with the coral I want to dip. It just took a little too much clown lovin and I want to help it recuperate.
