Chiller's X-10 once burned out, and kept the unit on "on" for a day. Tank temp went in the 50's ..... lost 1/2 my stuff, including some nice fishes :? Switched over to the heavy duty X-10s.
Oh my 50 gallon (about a decade ago), the return pump failed and I found most of my animals in pretty bad shape the next morning (lost 3 fish). Which pump? Rio, of course. No more Rios.
Heater once exploded when the water level was too low (bubbles from the overflow bombarded the heater). Bleached my tank due to a combination of stray electricity and melted plastic. Titanium heater is on my tank now.
From every diaster, something is learned.
