Seachem Equilibrium Sealed Bottle??
Ordered from Amazon, I opened the mail pouch and the powder was everywhere because the cap was open.
There was no external seal, no internal seal. I can't remember if this is supposed to be sealed.
Also, the chances of the bottle coming unscrewed in the mail, almost ZERO. I cant think of anything other than sabotage by amazon employee.
Can't use this because it could be tainted. For all I know its a return that was filled with cement.
