    Interesting question. It all depends on what you are after......
    There is a definite correlation between growth rates and temperature w.r.t. sps corals. At higher temperatures, calcification rates increase significantly.

    http://www.hawaii.edu/coral/Okinawa%20Proceedings%20manuscript.pdf

    Imporatant to note the importance of increased flow associated in the test pools where temperature fluctuations, max temp and fastest growth rates were recorded.

    However, to those wanting to push the envelope to increase growth rates:
    http://www.ingentaconnect.com/conte...68263c7b6f7e2a46762c47745d58763c25532a446c7c4

    Only the abstract, so not sure on flow rates and origin of species tested.

    Was also reading some comments from Walt Smith, who advocates lower temperatures for corals from the fiji region. Cannot remember the exact temp, as the majority of our sps comes from warmer indo waters.

    Personally i fel that anything in the 24 to 28 degrees celcius is acceptable for sps.
    Also remember that many of us are keeping mixed reefs, often containing lps and softies from deeper cooler waters, so increasing temperatures to increase growth rate and colour will have adverse effects on these genera.

    Another thing to note is that with increased growth rates, coral skeletal density decreases/weakens significantly.

    I would not run my temperature at max to increase growth rates. Been there, done that, got the growth rates. BUT feels rather scary tiptoeing on that cliff. rather maintain healthy growth rates, stable parameters with a slightly higher temp of say 28 and still leave your tank with a safety net for those really hot days.

    my system anything from 26 to 30, But yes, i would be happy maintaining a steady 28, only interrupted by the occasional blip upwards and a downwards plunge with a tidal simulation....
