made up statistics
my made up statistics show that
20% of Tank Crashes come from component failure
50% of Tank crashes come from user error
30% of Tank crashes come from biological issue.
I find Heaters crack and leech after being in salt water for too long unused...
Old sand will crash a tank if its not replaced or stirred a good amount
User error is part of the hobby but when something is routine you expect it to go the way you want.
I betcha didnt check the salinity of the tank before you did the water change.. In this hot weather you might have evaporated alot.. a lot of salt spray.. your skimmer was pulling out a lot of waste.... might have dropped your salinity down a little lower than normal.. then BAM salinity back up directly over the corals taht were just living at 1.019 or something back to 1.025/6... SHOCK... DEATH. meh.. possible your water change water's PH was too low or high caused a massive PH swing..
