I'm working on ideas for a heat exchanger in my 275 gallon tank, but I'd like to know what to stay away from!

If you are planning on just storing prefiltered and dewatered VO in the tank most any metal will work ok. If you are planning on storing WVO with acidic water still in it...look for metals that do not react with acids much.
