sps growth vs temp

[power boat jim]

Has anyone observed what the optimum temp range is for sps growth. Would it seem logical to assume that if you kept the temp in the warmer range that metabolism would increase and speed up growth? Any thoughts?

 

[Allmost]

yes

optimal/max growth at 84 F

I will try to find the paper stating it.

THat would be good. I noticed a decrease of growth in some coral after switching to LED I dont believe its the lights I believe it is now the tank temp. It was 82 -85 with halide it is now 75-78.

Intresting why does everyone keep temp at 78 ? Mine goes between 76-78 with rancho controller should I raise it to go between 78-80 would I notice a difference

84* seems very high. I've seen RTN at 85*

mine is at 80-81 degrees my reef loves it

I think some of it has to do with what your corals are used to. 85 is high if you keep your tank at 76-78. I do not run a controller and have had swings of 5 degrees and no effect to my coral. A lot of people who keep their tank temperature within 1 degree of a number have reported losses when these types of larger swings happen. I think a lot of this hobby has to do with maintaining YOUR conditions. I have seen SPS tolerate high nitrates - notice I said tolerate and not thrive. I have also seen perfectly good wild SPS die for no apparent reason. I tend to believe this is them not being able to adapt to the different conditions. This is why people are turning to frags more and more often. Corals that are acclimated to the conditions in OUR tanks tend to do better. I think this helps explain why you can get a coral that is growing perfectly well in one tank and then take it to another tank that everything is doing well in and have it die. I would not be surprised if you could raise your temp slowly and acclimate your sps to handle higher temps without issue.

I attempt to keep my reef around 78 degrees - I only worry if it drops below 74 or above 82. For example - I turned my heat on finally a couple weeks ago because the tank was dropping to 74 everyday (not too shabby - made it until daytime temps were in 40s before turning on my heat :celeb1

another thing to add - many times things perform their best when on the verge of failure. I have no idea why it works that way, but it could very well be true with nature.
