Taking Heat about my heater

[Randall_James]

In past threads I have taken a bit of abuse over my allowing my tanks to bounce around on temperature and typically not using a heater...
My theory was that a "to stable" of a tank weakened corals making them more susceptible to disease and bleaching.. By stressing the corals, they would in fact be more tolerant of swings in tank conditions should some type of other issue arrise.. (I only had personal observation on this)

This was in part backed up by a couple other "casual" observers and now it appears that there is some authoritative information on this subject...

A December 2007 study by the Wildlife Conservation Society found that corals in "tough love" seas with wide-ranging temperatures are more likely to survive warming waters than corals in what had been stable environments.
