Hi all,
Over the past year, I have been struggling with an on-and-off issue with my sps corals. I have looked through countless threads to try and determine a solution but I have yet to prevail. The issue I am having has been very difficult to pinpoint, my system will be doing great for a month of good growth on all corals, and then poof I get these weird areas of tissue loss on some of the sps corals. I don’t believe it is stn because the affected area never spreads and the tissue repairs itself within a couple of weeks. This is a repetitive cycle that affects almost all of my sps corals on and off but never more than 2 colonies at a time. I have maintained these parameters consistently throughout the past year plus.
Alk- 8.5-8.8 DKH (Trident/Hanna)
Cal – 425-450 ppm (Trident)
Mag – 1300 ppm (Trident)
Nitrate – 10-12 (Hanna)
Phosphate – 0.06-0.8 (Hanna)
Daily Ph 7.9 – 8.32 (Hanna)
Dosing –
All for reef and Kalkwasser (Trying to wean off AFR)
NeoNitro
NeoPhos
Once a week Acropower
I have had aefw before so I know what to look for and there is no signs of bite marks on any of the corals, I have tried dipping the affected corals and nothing but pods have ever been discovered on the plugs. All of my sps corals have plenty of flow and at a minimum 275 par, max around 350. I do bi-weekly water changes, and feed 3 times a day. At this point, I have no idea what could be causing this issue. The one thing I have noticed is that the tissue loss is always in areas of the most flow. Im not sure if something is burning the tissue? Could too much AFR cause something like this? Has anyone ever experienced anything like this? I have been stumped for over a year now. Any advice would be great!
Thanks!
