DI resin question

[ebow3d]

I have bought new DI resin from eBay: http://www.ebay.com/itm/230594171385?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

Now, it is already orange colour, as in the picture. However, I was under the impression that DI resin is blue, and turns orange as it is used. So, is this resin okay? And if so, how do I know when it is exhausted?

It's exhausted when your tds are not zero.
Color changing is a nice feature but it costs more, maybe this one does not provide that function? Also, you have to pack it into the can carefully to ensure that the water cannot create channels to simply flow past the resin, so a bit of research is in order if you intend to fill your own canisters.

These are packed by professionals with a new seal on the can so you don't have to set the foam donut and lubricate, I find them worth the extra $5-10. Yours will depend on your unit I suppose

Oh, thanks for the info. I've got one of the horizontal blue canisters for di, and since I've already got the resin, might as well try it tonight.

I should probably buy a 10" upright canister.

I use di resin at work for a different purpose and it is orange out of the box.

The color of "color changing" resin varies by the resin manufacturer.
