Temperature hitting 81 degrees on my aquarium

[ghazni]

Hi there,
My aquarium is hitting 81 degrees in last 2 days because of warm weather here in Redmond, WA WITHOUT heater. Anyone seeing similar temperatures in Redmond\Seattile? Is it bad having low 80 in temperature? Do people use chillers?

I have 29 Gallon Aquarium with Aquac Remore, and 2 MJ 1200 to circulate the water.

Thats really not anything to worry about. I keep my reef tank at 80 year round. It gets up to about 81 before the chiller comes on.

I just came back home to see the temperature and it's 82.1 degrees. My light on period is 12:00 pm to 12:00 am. Should I reduce or change the hours or timeperiod?

 

[Jeff]

I wouldn't worry even at 82. I try to keep the variation as small as possible but 82 is still ok IMHO. Do you use fans to try to keep the temp down?

Try reducing by two hours and see.

a fan in the sump along with one in the canopy should give you the few degrees of temp pull down that you need.

82 isn't dangerous, but you're getting near the top end; especially for fish. The ideal temperature is between 75 and 78, but you'll notice a lot of reef tanks out there around 80-82. That's mostly due to the lights and heaters we have, but summer temps play a large roll too. If they rise anymore than that go ahead and cut the lights a couple hours less. Using a fan helps a great deal as well.

Chillers are great for larger tanks where you have an enormous amount of lighting and pumps, and where you can justify the cost of buying one. For smaller tanks go ahead and buy a room air conditioner. Why should you suffer while the fish stay cool, when you can both stay cool?

totally agree. Reduce the photoperiod by a few hours, try and run the lights when the day is later so it is less hot and throw a couple fans in. The fans will make a big difference - you can tie them into the timer for the lights so they only run when the lights are on.

Ihave a fan on canopy, but I will go to HomeDepot to fins some small fans that I can clip on to Aquarium

You will get more evaporation with the increased air movement on the tank, keep an eye on it.

I run my tank at 81-82 degrees all year. However, you might want to alter the time your photoperiod comes on and off. Not only reduce the totla length of it by a couple of hours during the summer, but if you run it starting later in the afternoon when it is coling off outside it will save you some heat and electricity.

My lights run 11 hours (3 MH 250w) and I have a chiller and one fan up top and one on the sump. My tank stays around 79-80 degrees. Wal-Mart has clip on fans for less than 10 bucks. That's what I have and they work great.

Here in the heat of the midwest my tank runs at 82 most of the summer, I've been told that temperature shouldn't ever top 84. I do have a friend who's tank runs 85 all the time and has had no fish or coral loss.

I try not to let the tank get above 81F, which is when my small chiller turns on. I also have 2 fans blowing on the sump, and fans in the canopy. The air inside is normally set to 76, but sometimes I turn it down to 74F. My nano gets in the upper 82s.

Brian - what temp do you keep the house at? Last summer without the chiller my tank ran in the upper 82s low 83s.

 

[jetaero]

My tank runs at 75, I keep it in my room, with a 4,000 BTU AC, the room stays around 70, there isn't much power usage out of it either. My other tank I just put a fan in the window...it keeps it around 78 on blazing hot days.

 

[plack]

all you probably need now is that small fan running across the top of the tank hitting the water you said you had one on the canopy I assume that means inside drawing heat away from bulbs really a small fan will reduce a 60 gallon down to 75 from 82 with no fan at my house be prepared to fill up the tank or sump more from the evaporation rate

 

[btuck]

Nikki--We keep the house close to 75 or so

 

[NaH2O]

Thanks Brian - I was curious as to what would happen if we set the house air even cooler than 74, but on really hot days, I suppose the air conditioner would run all the time.

 

[btuck]

Yeah I am sure that it would, when I lived in the south we didn't set our air below 80 for that same reason.

Ghazni,

If you can visit Fred Meyers, they have these clipon fans for 6 bucks. Just bought two today. Make sure that the fan blows directly on the water and not the bulbs of MH. (do you use MH?). This is more efficient. It can chop down 3 degrees in my 2x250mh setup on a hood. This is just one fan.

Also make note that you will eat up a lot of water as evaporation... so you should take not on this one.
