SPS temp

[Timidfish]

Ok I am truely sorry if I missed this and couldn't find it doing a search. I am cycling my tank currently and am planning on a mixed reef lps and sps, I was wondering how much temp swing is acceptable. I can keep it around 78 during the day and at night it gets down around 75.5-76, I know the ocean gets a tad cooler at night but I was wondering if this is enough to worry about. I have a heater in the tank but the tank is downstairs in my 2 story house, so the thermostat is set a lot lower at night then during the day. I was thinking about adding a second heater in the sump to heat up the return water.

Thank you for any advice you can give me, a good friend of mine said this is too much temp swing for sps to survive, but I am getting all the info I can on this before I buy a second heater for no reason right away.

Personally 75 F would be a little too cool IMO. I'd shoot for 77-78F at night and <82F when lights are on.

And I should re-phrase or clarify my comment about 75F being to cool....I think it is acceptable as a low temp but not ideal and I have personally been keeping my tank around 77F-78F controlled by Apex at night to about 80-81F for a maximum temp during daylight and have seen no issues.

Thank you all. I will read those tonight at work. I didn't think 3 degrees would be enough to do damage. But to be honest I am not sure and want to make sure this stuff lives. Not dies off on me

MisterP I read that article. Thank you it seems my worries are nothing to be cornered over. I have no issue keeping it over 75 but was worried because to do it my tank gets above 80 during the day. Normally to keep it over 75 it runs at night 77-78 during the day its 80-81 give or take a half eother way. But I thought it had to be at 78 so that was where I was fighting to maintain it. Like today its at 78.8 but it drop to around 76 or so according to my wife who looked at it before going to be last night.
