Clean water rez cooling methods?

[IhatePM]

Trying to figure out if there is a machine, or something that I can add to my 275g ibc rez that can keep the temps under 70f in the summer months? Currently running diluted pool shock. There has got to be a better way!

A wort chiller would do fine, I'd think. Finding a water chiller big enough to make sense will likely cost a big fortune, a wort chiller will be slightly cheaper.
