It has driven me crazy for the last 4 days. My SPS was attacked with a case of RTN. My SPS have been doing great for the last 4 months. I saw a few of very nice acros showed signs of RTN. WHY? All the water parameters were good and I hadn’t had any sudden temperature changes.
I remembered, about 7 days ago I re-aquascaped the live rock. Moving the rock around might have triggered that toxic release and a result stress on the SPS. That stress probably made the SPS very receptive to bacteria infection. I immediately did a 20% water change. It was apparent I lost a lot of nice SPS. I did another 20% water change this morning and some of the SPS are again beginning to extend. I will do another 10% water change this weekend.
SPS is very tough to keep, but I will not give up. I will try again when my tank is stable.
