Definition of crashing

I'm just curious. People seem to use the term "Crashing" very often. And...I'm just wondering what it truly means when your tank is crashing.

Can someone please explain this term to me? Thanks, I'm always learning & seeking knowledge.

Most everything is dying in your tank and your parameters are way off.

It means that you have introduced something into your tank or something has died and has produced more of a bioload than your tank can handle. It is like when your tank cycled for the first month or so. It is an unintended cycle. If large enough will kill everything but the hardiest of tank inhabitants.

I generally refer to a tank crash as an event that would suddenly cause you tank to be unable to support life resulting in a massive die-off. This could come in many different forms, but a good example would be a heater failure, and a sudden temp change wipes out all the livestock.

Cascading death. Something dies and the pollutants from that death cause more death, and the snowball goes downhill from there. What starts the crash can vary from environmental factors, equipment failure, incorrect dosing, death of a toxic critter (sea apple, etc.)..

agree with both posts above. Doesnt matter what causes it, but everything starts to die off.

Thanks everyone! I hope it never happens to me! Actually, it happened to me in the late 1980's! That's probably why I got out back then. But, I'm here to stay!!

Test all 5 params at least weekly (I recommend daily, for a new reef) If FOWLR test 3. And keep a logbook. That makes it very unlikely you will have a crash unless something intervenes like a major power out. The best protection against that eventuality is an available generator; second best is understocking, which is a good policy anyway.
