This is my first time hearing about these "magic" blocks but... wow what nonsense lol

Quote from Amazon "This is not a slow-dissolve or time-release product. It dissolves only to replace depleted elements." Which sounds not possible at all...

It’s not actually impossible. Maybe it really has a mini ICP-MS and 16 little dosing pumps inside each block. lol

I want to see someone throw one of these in a bucket of sea water and show that it never dissolves lol
Nice. Proof without any testing needed.
