1. Anyone with that northern midwest accent is hard to take seriously (Oooh yaaah rayray did grow up there tooouoo ya betcha)
2. Ive always condidered heaters the most dangerous part of the reef tank: blowing up, staring tank/house fires, electrocution, etc
3. I use titanium heaters with their own controller, then plug that into apex for a second layer of safety, then i put it in my sump where i can see it with the web cam daily
4. Despite all that, i usually keep it unplugged. I generate heat with internal pumps, UV, and HID lighting
YMMV & such
