Tank Crash...What are the causes?
What are the type of things that cause a SPS tank to crash, where you lose most, if not all of your corals?
Inquiring minds want to know

One of the reasons I have two seperate controllers on my tank (Reef Keeper & AC II). I trust RK's temp probe more than AC but I run the lights off the AC so they shut off if the temp exceeds a set parameter. I also make sure there is at least a 2 or 3 degree temp swing each day. I read something one time that made allot of sense to me. If your corals are acustomed to less than a .5 daily swing, then a 4 or 5 degree spike will be much more traumatic than corals that are used to a 2 or 3 degree daily swing. Stress & shock seem to be a big deal IME |

Pumps getting clogged and causing heat to rise do to friction. Heaters being stuck in on position all of a sudden. Calcium reactors going out of adjust.

I've had many crashes in many tanks I also believe is temp. Thus controllers are great ideas(turn off lights)
U can take care of alk/calcium/r/o malfunction/ somehow with water changes and so forth but if your tank cooks for 8-10 hrs u get this.  [/IMG]

I second this one, I am a strong beleiver in not making everything to constant. I also let my temp swing two to three degrees a day! |

Anemone spawning events, especially in females. I just lost 10 and 12 year old colonies as a result

There are so many causes, which we can point fingers in a certain direction, I am also a fond believer, that if you baby the system, for a long duration of time, minor swings, in especially alk, salinity, temp, pH, and all other parameters, can have a much larger effect on a tank full of cancer corals per say. Its as if you have them on life support, and as soon as the catch wind of a minor swing, they crash and burn, especially if they started from a frag and grew to full sexual maturity. Too many factors to list, but having flat lining parameters that never fluctuate is great, until you have a dip, results will be present, i.e. bleaching, burning, STN, RTN, or if your lucky nothing at all until next dip. Here is a great line I found floating around, about coral reefs and effects that cause total failure and reef bleach outs in tropical wild reefs, maybe we can learn from this?
"Coral bleaching is the whitening of coral colonies due to the loss of symbiotic zooxanthellae from the tissues of polyps. This loss exposes the white calcium carbonate skeletons of the coral colony. Corals naturally lose less than 0.1% of their zooxanthellae during processes of regulation and replacement (Brown and Ogden, 1993). However, adverse changes in a coral's environment can cause an increase in the number of zooxanthellae lost. There are a number of stresses or environmental changes that may cause bleaching including disease, excess shade, increased levels of ultraviolet radiation, sedimentation, pollution, salinity changes, and increased temperatures." |

im also a believer in letting the temp in my tank swing. it swings about 3 degrees throught the day. from about 77-80.
ive argued with a lot of people about it and most people say it just puts the corasl under constant stress. but if you think about it, in a lot of tidal ares where sps corals are exposed to low tides, or even exposed to the air for a few hours everyday, im sure the temp swings more than 3 degrees. besides pests like AEFW, i believe alk swings and major temp rises or drops are the major contributor to tank crashes.

Human error probably 95% of the time. This goes with fish deaths also. Temp. , alk, spike ect. are the results of these mistakes & errors. It's all on the hobbyist to maintain & design a system that doesn't fail.

temperature, kalk disasters, losing power out of town
are easily top three reasons for tank crashes |

If I remember corectly then DNA's TOTM http://www.reefkeeping.com/issues/2004-12/totm/index.php crashed because of flatwoorm exit.

I have used it on my 60gal but my tank was not heavily infested and I did 50% water change,
I bet it's a bit more difficould when you have 350gal heavily infested tank! sorry to hear that it bit you as well! |

A better question might be what has not caused a tank crash. I've never heard of a meteorite impact destroying a reeftank ....
