Levels and lighting need a tweak or to and The corals need some help as I had a nitrate problem but here it is anyways. And yes there is blue gravel in there thats what happens when you let a girl your dating aqua scape and she sees a bag of blue gravel under your tank stand to late to fish it all out now so i just left it.

I would post in the chemistry forum I am not 100% sure but I believe the colored gravel will leach toxins into saltwater
