This is somthing ive been looking into a lot myself actually, and curently experimenting with myself.
Personally its a great way to balance your nutrients.
Allows nutrients to be taken up naturally by corals/bacteria/etc.
Other things ive picked up on from researching other peoples experiences is...

Ive heard of more stability with PH by not running a skimmer - Mikeymikemike.
