This morning I woke up to an alarm from my Apex, low temp in my frag tank. Found that the return pump had stop around 4:30 this morning. I have a back up so that's not my question. My heater is in the sump of this system, a 100 gallon stock tank filled with live rock, over 100 lbs. The display is a 80 gallon DeepBlue with just a little rock, maybe 20 lbs.
The display got down to 75, all coral and fish, only 2, a yellow tang and a damsel, are fine.
When the return stopped, the heater kept heating the sump. The temp in sump got up over 94.
I do expect die off in sump.
Think I should keep sump off line for a while to cycle or think it's safe to just cool it down and get it running again?
Any input is appreciated.
