What temp do you run?

[MitchM]

Temperature IS important.

From the article I posted:

The most rapid growth of most corals is generally around 27°C to 29°C (80.6°F to 84.2°F) (Barnes et al., 1995; Clausen and Roth, 1975; Weber and White 1976; Coles and Jokiel, 1977, 1978; Highsmith, 1979a, b; Highsmith, et al., 1983).

and..


A recent study shows how differences of only a couple of degrees Celsius determine the distribution of Montastrea annularis populations in the Gulf of Mexico and in the Caribbean Sea, proper ( Carricart-Ganivet, 2004 ). In this case, the no growth lower limit of zero calcification occurred at 23.7°C (74.7°F) in corals from the Gulf of Mexico and at 25.5°C (77.9°F) in corals from the Caribbean Sea.
