What SG and temp do you keep in your tank at?

[Jan]

I've read that SPS do best in somewhat high SG, 1.026 and above, but what about a mixed reef? What do you keep your SG at and why? What are the benefits of high and low SG? How low and how high are safe? What about temp? I've seen people keep it as high as 84 and as low as 77 degree F. What are the advantages or disadvantage, if any? What's the safe range, high and low for reef? Thanks.

mine ranges between 77 and 83 and 1.025-1.026 for SG

I always kept my SG between 1.025-1.026. My temperature ranged from79-82. I was keeping LPS and SPS with good results.

1.026 - just because that's where it's recommended. http://www.reefkeeping.com/issues/2004-05/rhf/index.php

 

77.0 at the low end (heaters come on at this temp and push temp up to 77.5); 77.8 at the high end (fan comes on at this temp and push it down to 77.2). I did this to slow the metabolism of the various organisms in the tank. I used to run the temperature in the 80-81 range, but decreased it recently. I've never had much difficulty with either range to tell the truth. RHF (in the article linked to above) runs his tank between 80-81. I may increase it again just to see if I get any change in coral growth rate and coloration....

The reefkeeper keeps my tank at a almost rock solid 79.5.

 

Salinity is 1.025 - 1.026.

[Jon Lazar]

The ocean reefs average 35-36 ppt salinity (1.0260-1.0265 specific gravity) and 82F

 

I keep my reef at 35 ppt salinity (1.0260 specific gravity) and 80F +/- 1

my old tank would swing 3-4 degrees per day and it was not an issue.
