Sodium thiosulfate pentahydrate?

Does anyone use this in their tanks and/or ponds for dechlorination/metal detox?? If so, is the anhydrous product (crystals) sold in pool supply stores sufficient or does it need to be scientific grade? Thanks!!!

Never tried it. I've been thinking about trying seachem safe when I run out of prime.
