Tank Cooling Thought

Got this link from my Twitter account

So of course the very first thought that comes to mind is I wonder if I could apply this to my tank. So instead of installing a chiller I was wondering could you add another section in your sump or plumbing an addition tank with water that would pass through some massive air injection for added control of the temperature of your tank? Would there be a negative effect on pH or other parameters?

Just thought I would through that out there since its Friday with 50 mins left of work.
