Where do you have tank temp at?
 

How hot do people let their tank get? Where should the temperature sit if you could keep it steady? How much of a variance is safe? I'm starting a nano shortly and I know that this will be more of a problem with it as I'm doing a DIY MH light.

I'm thinking on doing mostly SPS and LPS in this nano, do these corals perfer a certain temp?

I keep mine between 78-81, and I allow the variances. I think it allows a more natural daily cycle in the tank.

75 avg...range 74-77

80 all day long.

78-80

We were at 75-77 and just raised it up last night to 78-80. It seems to be holding steady at 80.

I keep my tanks at low of 78.0 and high 81.5. My avg. is 80.0.

Heater comes on at anything under 78.5
Fans go on over anything 79.5
I average at about 80-81 so far. We'll see what happens in the summer <gulp>

78/79 with the use of a chiller. Probably the 1 piece of equipment that had the biggest effect on my SPS, other than my calcium reactor.

I keep mine at alow of 78 to a high of 81. My heater keeps it above 77 and chiller keeps it under 81. I have some heat issues in my tank and when lights are on I don't need a heater in winter , it just keeps it from going to low at night. In summer don"t have to use a heater just the chiller and AC in the room.

I've got my heater set at 78, and it swings between 80 and 77. In the past, I've turned it up a bit in the summer because my AC wasn't able to keep up. It's not the higher or lower temps that stress a tank, it's the swinging of the temp that causes the stress.

Mine is at 80 .. with the heater coming on at 79 and the fan coming on at 81

bounces between 80 and 81

mines stay around 77 -79

Heaters are set at 76

Ranges between 76.0 and 77.5

The heaters come on at 78 and they get up to 82 during the day (84/86 in the summer)

78 to 80

75 never really goes above maybe 75.4 or so down to 74.8.

77.5 to 81.1 are my ranges depending on the ambiant temperature in the room. I never let it drop below 77.5 though.

almost always 75-77, depends again how long I run my lights
