Preparing chiller for sale - should I do anything?

[sushi]

I got a 1/15 hp chiller so I unhooked my 1/6 coralife aquachill. I am going to sell it once it is hot enough to test my new little chiller and make sure it'll suffice. In the mean time should I do anything with the 1/6? Obviously I won't tilt it from upright to get the water out or anything, but should I run vinegar or DI through it? If I was going to buy a chiller I'd probably prefer it left as is, with the tank water inside, but that is just me.

I've never heard this question before.

If it sits awhile, you might want to flush with fresh water, rinse with DI, and elevate the chiller and siphon out the last of the DI water hoping that most will come out. Evaporation will handle the rest. That should minimize the problem of corrosion or scaling from any salt water evaporation if it sits very long. 0.02
