Ok so I just had a post upset over my friends dejardini who was sick well, it gets worse. His whole tank is going down. Naso and a powder brown down, Coral beauty, 6 disbar anthias down... this sucks. The weird part.. his inverts and star polyps are fine. like nothings wrong.. his levels have obviously spiked a tiny bit now with all the death but they were fine before. It's a 150g. The fish just deteriorate as if in acid he said.. like scales fins just gone. Anyone have any ideas. He has a sump with live rock, filter pads, carbon, cemipure elite, a seaclone (crap skimmer) and crushed coral. the lights are PCs and I think he has a fluval 405 on there just for kicks. PLEASE anyone have any ideas? Could it be his tap water. does it sound like he's under conditioning? What would do this... ?????? he doesn't have copper in the water just fyi.
