80 except when it's really hot outside in the summer. On that day it's 82. :biggrin:

My own reef 81-83, SPS.

My Clients' fish only 74-76.

My Clients reefs 76-78. LPS, SPS, Softies.

Mostly LPS and some SPS, temps always at 77 in the cooler months and rises to about 82 during the peak summer months.

I submitted a vote 80 but it's more like 78-82. Warmer on a hot summer's day. I don't panic until well above 86 or so, but it's hit 90 a few times this year and things lived through it (although there have been times it hit 90 in years past and things didn't always live, so who knows). What do I keep? Umm ... your basic broad spectrum I suppose. Softies LPS SPS anemones etc.

I don't know why, but I like to think of tank temp in C. My thermometer reads 26.1C. I had to think for a couple of seconds what 26 was in F before I responded. I can think of volume in terms of gallons no problem (maybe because measuring tank sizes in litres seems weird, a litre is just too small ... might as well measure in terms of pints or something), but temperature I think of in C. Maybe that's because temperature in C is something tangible to me, e.g., it is 20C outside today, or it is -18C or whatever .. I always have to stop and think about the temperature when I watch a US station and they say "there will be a high of 5 today" and I'm like .... is that cold? I have no idea.

Incidentally, when I dived the GBR the temperature was 26C.

My tank varies from 80 at night up to 82 during the day. I keep my metal halide on for 15 hrs. Last month I had the temperature swing from 68 to 89 degrees for a day due to a faulty heater and some stupidity on my part :redface: .
I noticed the heater had quit in the morning and unplugged my fan to help the lights bring up the temperature since I my backup heater didn't work as well. When I got home from work the heat had gone up to 89. Everything pulled through it unharmed. :smile: Anouther lesson learned!
