super blue RODI water ?

[Zan's Aquatica]

Hi, i bought this from a well known high end LFS, it looks Super blue. It’s just RODI water, what’s going on? I had it in a plastic container in my car for a week (it’s been cold here) could that be it?

RODI water is not blue. what was it stored in? I probably wouldn’t use it myself.

I stored it in a Clear plastic portable/collapsable water jug !

It could be methylene blue.. maybe ask your LFS, it’s used as a general detoxifier for nitrate and ammonia and I believe it’s actually some kind of blue dye but not 100% sure.
