Check your tank temperature

I just got my 80 degree text message from the RKE. Fans are helping, but not enough. House is at 83. AC is on now :)
 
seems a little early to run AC!

maybe it's time to make some modifications to the system so you can turn AC off and keep windows open.

What's the temp outside..... like 77F??
 
I was fearful of rain and my computer is near the window, so I returned home to muggy tank room, all is well now. The ac is for my comfort I tend to like coldness.
 
Bahh... low 80s are fine for a tank. Mine usually runs around 81, but has gotten as high as 85. But for me... 73 or lower.
 
Unless you have decorative macro algae to worry about, low 80s should be just fine (the only things I've ever lost due to temperature swings were macros). I only worry if it gets over 85.
 
yea mine was 80 today when i left for work at 3 pm, fans and basement sump are helping.

gary, huge temp swing between buffalo and syracuse i saw. i guess you guys are niec and cool, we were mid to upper 80s and muggy
 
Gary, made it to 90F at my house. Thermometer was in the shade too. The sun was brutal today. My tank is at a warm 81.2. A/C will be going in soon for sure.
 
yeah, it was toasty out there today! I improved the fan location on the basement sump to cross the water versus general location. The upstairs fan needs a fan which has better aim. I'll have to build an attractive shelf and put two small fans on.

so yeah, there is room for improvement! The fans were thrown in amidst other things, really need to make them more permanent
 
I need to get some fans soon. I decided against a basement sump room, and the tank creeps up to 82 by the end of the light cycle, and that's with the house at 72-74 or so. Dang metal halides.
 
Dan, I don't remember if you have a controller. If not, you should consider getting one to operate your heater(s) and a fan or two. My RKL holds my tank temp to around a one degree variance. Meanwhile, stop at Walmart and pick up a cheap clip-on fan. Works great!
 
I had to kill my halides yeserday , temp went to 83 and now its 80 ... I had to put frozen 2 liter in sump and run fan but the temp went back normal after a few hours. Maybe time to look into getting a chiller. What temp will start killing? has anyone had a problem with corals dying from extreme temp and if so what was the temp?
 
Generally, 84F is getting dangerously high.

Eileen, I don't have a controller, but I am definitely going to add some fans ASAP.
 
*fish can't get Cryptocaryon simply because temps go up

*prolonged exposure to 84-85F can stress certain corals but many corals can tolerate that temperature indefinitely

Most of the corals we keep will do perfectly fine at 84. It really depends on what they are used to though. If you keep your tank at 78 and don't let it fluctuate, the corals will be used to that temperature. Even if you tank gets up to 83, it could be trouble. If your tank is used to fluctuating between 78 and 81 or 82, a jump to 84 or even 85 probably won't even phase your corals.
 
Imagine the heat that some corals deal with in tidal pools. Water temperature has to sway for sure. Does anybody know any good links to studies related to tidal pool temperatures? I can't seem to find any.

to be honest

I've never heard of any discussions regarding coral growth in tidal pools.
For the vast majority of corals, tidal pools aren't an optimal environment to grow and coral growth (if any) isn't remarkable.

I don't believe corals can be "trained" to do well in warmer than optimal water by allowing water temps to fluctuate.

Lagoon and reef crest species of corals are most likely able to tolerate temperature exposure extremes. Popular deep water corals (LPS such as Acanthastrea) are more sensitive to high temperatures and/or rapid extreme fluctuations.

When an aquarist allows temperatures to rapidly fluctuate or run constantly higher than optimal you're simply limiting the number of species you can keep.

Only those corals that can tolerate environmental conditions will survive.
