upper temperature range

[reachjohnnyliu]

I need to set the max temperature my house can reach before the a/c kicks on. What's the max I can set it at w/o hurting any livestock?

That would be somewhat dependent on the livestock and makeup of your tank. I would say ~84F would be okay for the majority of tanks, but for tanks with poor aeration, heavy bioload and species of deep water fish or corals, it might be on the higher side.

If you selectivity have shallow reef corals (this would be difficult since you would need to know precisely where the coral came from) and fish, can manage nutrients and have sufficient aeration, you might be able to reach temperatures as high as ~90F. Northern red sea can get 90F in summer for extend periods of time without any bleaching, but same temperature kills corals of the great barrier reef. So it all depends on livestock you have.

all tanks will run hotter than the room temperature, every tank will be different. My tank will run 2-3 degrees hotter than the room temp.

Yep.... Near the end of your lighting schedule measure the temp of your tank and subtract the temp of your local ambient (room temp)....subtract that difference from 83 deg f...that is the max temp your home should get..
Example...tank is 80f...room is 76f..subtract 4 from 83 so room can be set for 79 deg f max

74 max

My tank fluctuates between 78 and 81 daily. It's been that way for several years and no ill effects. I feed them well, and my params are stable, so the fish and corals don't mind. I have my AC set to 79. I do live in southern CO, where it exceeds 100 in the day and drops to mid 70's at night.

I have heard most reefs will be fine up to 84.

Mine is automatically turned on when the house gets 2 degrees hotter that what I set.
Works same with cold and hot, with a good heater, my variance throughout the year is max .5 degrees.

I look more for stability in numbers rather than any one level, although there are limits on that.

I am convinced that more the stability the better the colours and growth.

My SPS tank runs about 80-82. Seems ok. I don't try to control the tank temp. It's just a function of the ambient room temp plus 3 or 4 degrees of mostly pump induced heat.

With T5s my tank seemed to run 4 degrees over ambient with a DC return pump and vortechs keeping most of the pump heat out of the water.

sounds like i dont need to worry about ambient temps to much. my tank temp hasn't gotten over 81 yet to date.

You can see where I turned the heaters off. They had been set to come on at 79.

I keep the home ac at 78 day time, and 72 night.

Here it is

My tank has gotten as hot as 82 and never had any problems. I keep the house at 78

75-86 throughout the year. No problem...

One side of the spectrum in summer, the other in winter.
