Just curious if malachite green will stain acrylic tanks or not ?

What are you using it for?..
If enough is used I would think it certainly could stain acrylic

It will stain seals for sure in sufficient quantities.
I have only used this in freshwater, did not know there was an application for it in salt.
What you trying to fix?
