Although I have kept fish for over ten years I am brand new to Marine.
I recently bought a Juwel Vision 260 that came with 50kg of Live Rock, a Lipstick Tang and Common Clown. It had 2 years of concurrent mature water in it and was running using a Protein Skimmer, built in Juwel filter and power head.
I have added a Arcadia Luminaire with 4 T5 lights (2 white, 2 Blue) and last week added Devil Fingers and a small colony of Button Polyps.
I'm concerned that the coral is not thriving as its condition seems to be worsening (although the change is subtle and could be my paranoia).
