DI resin colour?

[mark]

Been using the stuff from Aquasafe and was always green and turned orange after use but just opened up some from a bulk supplier and see is bright orange right from the start.

Is there indicating/non-indicating resin? Was just in a garage bag, does this stuff degrade in air?

Yes, it does. Or more accurately, it's reacting with co2. Don't quote me but I THINK it's still OK to use. It just won't change colour when it is exhausted.

Hey Mark just keep an eye on your tbs meter if you have one. It seems to tell
me when to change my di resin , tbs levels go up.
