My Darkness Awakened Aquatank has POW 8

My Break of Dawn Aquatank has POW 11

The text is the same.

Which POw is correct?

Both are correct.

One Aquatank has 8 POW, and another Aquatank has 11 POW.

What it really means is that the stronger Aquatank is replacing the weaker one, that's all.

Wait, seriously? They don't do MRPs here, and my old aquatank is actually worth less than the new one?
