Gee wiz great catch! Have a great trip!I finally set up my InkBird. Doing so made me realize my thermometer was wrong, and my tank had been at 87 for at least a week. My heater failed and never turned off. I was wondering why my hammer coral was dying, and why my tank evaporated so much water in a day. It all makes perfect sense now. The tank is now at 80 degrees, so hopefully my hammer coral starts to recover. It was just a stupid mistake I made. But luckily my leptoseris looks fine; which is my most difficult coral. All my fish are fine too. I leave for vacation tomorrow, so I am going to do a waterchange today. Fingers crossed everything goes well.
