This Hobby is so frustrating.. Past 2 Month things have been on a steady decline. I am unable to pin point any particular reason. I have a redsea Max 250 with 2 Cree Lumia 5.2 LEDs retro fitted in the hood. 6 or so weeks ago I lost my BT trigger. NO signs of disease no color loss.. Just found him dead one morning... My Scoly has been on a steady decline no matter what I do it keeps retracting. I have moved it into super low flow/low light areas as recomended and it just keeps retracting. I am Losing one of my Rainbow Acans and just lost my blasto.. Yet My other acans, zoas, ricordias, torches/frogspaws, clam, and pearl bubble all appear to be doing okay. Oh and 3 RTBA.(my one split). And now it appears my Kole Yellow Eye Tang is on the quick decline. He is not eating and looks think and color isn't good. Water Now I do a 10 gallon change once a week. I also clean my Protein skimmer twice a week. I use RedSea Salt and RODI water. I test the RO water and its clean so filter is good. I don't have any issue with Algae either. Tank stays clean. I have tested with Red Sea Test kit and Salifert. I even took it to my buddies fish store and he tested the water and said only thing that was a bit low was the ALK.. Dosing I do dose my tank with RedSea Reef energy Part A and B Daily. I dose about 2mls a night of each. I also to up my alk been using Kents to raise that. 1.026- Salinity 7.7alk - has been going up since i have been adding buffer 8.2- PH Temp 81 400 Calcium Feeding... I feed once a day. I use frozen reef frenzy and also use Reef Smoothy to spot feed corals at night. Filtration. I have 2 units of Chemi Pure. I use a bag of purigen and just some filter floss. I change everything every 3 months or so. So I am at a complete loss. I have no clue what to do in this case. The only thing I haven't investigated is my lighting. I did swap over to Cree Lumia 5.2 LEDs but been running them for a while. I have them on a low setting so things don't appear to be bleached and some corals are really growing. It also appears I have a burst of Copepods in the tank. At night I see them everywhere. Least thats what I think they are. I removed a worm from the tank the other night and now noticing the copepods.. Here are some pics of those things.. If anyone has any thoughts let me know. I am just at a loss. Thinking this will just be a slow end of everything in the tank. I just don't know what I am doing wrong.
