The 'Sound of Silence'?

This morning, as I unlocked the main security door there was a dreaded sound of silence? No pumps!
A small pump on the Foam Fractionator had melted causing the circuit breakers to trip and all power to the ARC was out. No re-circulation, no aeration! Only 2 Bass had died. All efforts to restore power failed and our electrician was called in to restart the system.
Not sure of the cause of the burn-out of Pump 1 on the Foam Fractionator? The pump takes water from the sump into the skimmer? We will check warranty conditions.

Worms fed well! Plenty of scraps from Christmas lunch/dinner.
