Hello,
I am new to the forum here and looking for advice/suggestions on what may be going on with my tank. I have a 200 gallon Elos tank with SPS/LPS mix and no softies. I am running a Zeovit system with activated carbon. I dose zeostart daily, zeobak and zeofood twice a week. I run calcium and alkalinity on my apex DOS. For stock, I have 3 small clown fish, coral beauty and purple dotty back. I had a larger Naso Tang that recently passed. I do 15% water changes every 2 weeks. I always aimed for a low nutrient system and by my parameters you can see below I believe I achieved that but perhaps I have gone to far. This week, I began to see receeding tissue on 2 chalices, 2 blasts, an Acan and a favia. Acro and birds nest seem fine. This has made me think I have gone to far on the low nutrients. I am thinking I might need to increase the bio load of fish and feeding but truly am not sure and certainly want the balance of healthy LPS and SPS. Thank you all in advance for your help.
Brian
