Looking for more information regarding HLLE in tangs. I have a new tank that is going through the ugly phase. Watching for any signs of HLLE in tangs. From what I have read “poor” water conditions can be a cause. However, there isn’t further detail as to if that is concerning Ph?nitrates?phosphates? My tank is definitely not looking hot right now. Trying to manage the diatoms but want to make sure that isn’t considered “poor” water conditions. Any parameters that can effect HLLE I should be monitoring more closely?
