Thanks guys! You're too kind. Honestly, I see this tank every day (every day!!) and I don't think it's as nice as these pictures portray. It's an odd effect for sure.

@Levi - Thanks man. In hindsight I am thinking that most of my SPS issues were PO4 related. I think just because a test kit says it's low enough doesn't mean it really is low enough. Things still aren't 100% these days, I lose frags or have recession here or there but I really notice it if I let the GFO slide for too long. If I replace it weekly, things just look, behave, and grow better. If I let it go to two weeks it's hard to say how exactly but it just becomes noticeable and there's an almost instant bounce back as soon as new GFO gets put on. 1 cup per week seems to be the magic amount.
