Pump controller fell in water

[boise brewer]

So my controller for my Nero 3 fell into my sump plugged in while at work. When I got home, all my corrals were closed up. My fish look ok. But all of my corals are enemies, etc., are closed. I did a 30% water change and added a bunch of carbon any other recommendations please help.

I don’t think anything in the controller could leech out in that short amount of time. I would guess it is more of a lack of normal flow. Or a jolt of electric current that made them upset.
