Not that I would discourage this practice, but I thought the same thing and 3+ years in my tank still has PO4 issues if I don't have massive amounts of money burning in a gfo reactor, er, I mean, if I don't have massive amounts of GFO being replaced every couple of weeks.
I would instead encourage a healthy mixture of rock-that-hasn't-been-dried-for-too-long in the tank as well.
