Came home to a Sauna! Advice?

[scherzo]

Controller has saved me a few times. If you go away then a controller is pretty much a must have. I have my autofeeder controlled by my apex as well and will sometimes dial back the feeding if I am away. I have a fresh batch of saltwater on hand just in case someone has to do a waterchange while I'm away (only for emergencies)

I also have a camera on the tank so I can see what is going on.

Then someone who I can call and walk through some simple things to do to make it work.
