What exactly can be expected of chlorella? Does it chelate mercury, or just stir it up?

My wife bought some, and threw 3 capsules each into our mix of supplements one day thinking it would be a way to continue detoxing mercury.

About an hour later my ears started ringing like I was inside a church bell. This lasted about 24 hours before it tapered off, along with a touchy disposition and foggy brain.

Advice?
