will water temperature = air temperature?

as the subject says, living in south florida. We usually have the house around 78, but during the day I bump it up to like 85 because no one is home and A/C is expensive. So if I get like a 12 gallon nanocube, is my temp going to go up to 85 every day or does it not work like that?

 

it will actually be higher then that because your pumps and lighting produce heat.

also water takes time to gain and loose heat, so if its 78 degrees 12 hours aday and 85 12 hours a day, it will most likely be around 80-83 degrees most of the time. however you also need to add in the heat the equipment produces also as said above.

 

well it would be most likely a 12 gallon nanocube. they have power compacts, I believe they don't do much heat. so would that be too high of a temp. probably 85 for 10 hours, but of course it takes time for it to get up to that temp. then 14 hours 78, maybe 76 for like 7-8 hours of the time. when we are sleeping.

 

I don't know, I would tell you to set it up and take the temperature after a day or so.

 

well I'm trying to figure out before I buy. I can't afford a chiller to go with it, and spending a ton on electric is not an option either.

 

most people with heat problems put a fan above there tank to blow air across. it will drop tank temp 1-3 degrees.

However I don't know if you can do this with a nano cube, and it increases evap.

 

i would think if you had a ceiling fan in the room and had an open top tank you would be ok..

ive seen tanks fluctuate temps with no ill effects..naturally most of our corals we have are in 83ish degrees water..depending on whether the corals are deep water corals..

i would say you would be ok..i turn my ac off everyday and i live in louisiana and my tank doesnt get above 80degrees ever..and you know how hot louisiana can get..

 

okay, so thats not too bad, tank would be closed top, I could put a small fan over the back compartment I suppose if needed. but doesn't oxygen get depleted when temperature is higher? I thought fish have harder time breathing at the higher temps?

 

yeah they do but as long as you have surface agitation then you should be ok..i have always ran an open tank so it could be a problem if it was closed..but there are tons of mods for tanks to fix things

but my tank doesnt get over 80..i guess if it got really hot for a long period of time with no agitation then yeah my fish would prolly die..

and i run a halide with no ac during the day in louisiana heat and my tank stays at 80..78 at night
