Share 'cloudy ferrofluid lamp'

I have an Inspired Designs ferrofluid lamp. The other day, I noticed the liquid in it is rather hazy. I would like to replace the fluid. I did this once with a cheapo gas pump lamp, using distilled water and surf from a goo kit, and it went from barely visible to crystal clear. What I want to know, is it possible to do this with a the ferrofluid lamp, or will it mess things up?
