So I came back from my summer holidays (18 days out) and my main worry was that my fish where going to die because they were used to frozen food, out of 12 fish, 4 of them died (the pickiest ones with food). I put 2 automatic feeders and one malfunctioned so it could have been even worse. But my surprise comes when all my SPS have died, they are now totally white. I had about 8 beautiful pieces and all have died out. It surprises me because I have 4 T5 lights that are programmed automatically so the lights turned on and off, exactly the same number or hours as before. The only difference I can think off is "natural light", because I closed all the curtains so people waling by outside the house couldn't see if there was people or not inside, could this be the reason for the SPS dying? It is a pity because even they were not big (no mother colonies), they were very beauty like green and pink bird nest and they were thriving. Most of them were taken in the swap event and also given by a pair of other supporting members, I was hoping to grew them to start them fragging for other members. On the other hand, the soft corals, they did mostly well, didn't grow but also didn't die. Only thing that kept growing were the RBA anemones.
