Return pump seized for 3 days... Can I replace impeller?

[nerdz]

Came home to a high salinity, 68 degree display tank...

Some fairly heavy coral/fish losses.

Anyways, pump was plugged in and not spinning for 3 days. Impeller was seized with calcium. Will main body be okay, or do they burn up?

Its a Mag5 and I cant get the shaft out of the magnet. If body will be alright, I'll pop down to JLs for a new impeller

It was pretty fun watching my wifi controller on vacation show temps creeping up to 87 degrees. I guessed:

-heater stuck on
-MH stuck on
-ATO failed> sump ran dry
-Fried pump raising temps
-failed return pump

Turned out the be the return pump.

Lots of fun things to ponder over the last days of my vaction!
