Yes that's ice that I've broken up this morning. Freeze protect was running last night but sounding very bizarre, with the fountains being very sporadic and lots of gulping sounds. Finally at 2am I bundled up and went out to check on things.
The water level in the pump was very low. I switched to spa mode and it filled right up and ran normal, but in pool mode there was very little water coming back into the pump.
Unsure of what to do at this point at 2:30am and 20 degrees out, I shut off the breakers, pulled the plugs, and drained all of the equipment.
It's going to warm up tomorrow so I'm hoping that I can minimize damage by getting things running again.
