1) RTA got stuck into power head. Discover early. No nuke, just the unforgetable tasks to remove the
RTA from the powerhead
2) Main return pump down. Discover early. Lucky got standby pump.
3) Chiller pump went down. Temperature shot up to 30+ with MH on. Saw corals not opening as they
should. Quickly off all lights, put in standby bottles of ice and again, have standby pump. Took many
hrs to bring temperature. Hammer melted off.
But my worst fear is that all this happen and I'm NOT home
