I just phoned home and got my 9 year old to check the temp. She says it's at 83.3 Farenheit. Farenheit I ask? Yes daddy, that's what people use instead of celsius, she says :razz:

I guess the fan being on helped. I also raised the lights about 4 inches higher.

came home last night to a temperature of 94. man oh man. my tank is hating me. everything is haywire in there. one death, and it may be causing a domino effect. only had actinic on all day today hoping to get temp down, but temp is still at 88. damn apartment!!!!!! gotta get back to the tank

Man, you gotta buy a fan, quick!! I'd do a water change also because of the death. And while it sounds funny at first, use warmer water fr the change...don't want to shock things with coooler water. Get a fan right away!!

hahah, thats priceless.. love kids..

:eek: number one reason I hate appartments. I hope everything else is ok :frown:

same thing happened to my tank last night. 85F at 5PM. I put a large fan in front of the sump and in the morning it was a cool 78F. the fan has been on all day MH on as well and we are sitting at 80.1F right now. I think I'll rig a fan to blow directly on the sump surface.

Good luck everyone today and Saturday are gona be hot :redface:

I only know celsius myself. Your daughter must be watching too much American TV. Its always Celcius whenever we watch the Vancouver weather man. It is suppose to be 33C today according to the weather person. So, at what celcius will my corals start dying? :lol:

Sam, I know for sure at 82 C they will not be real happy!!

I am so glad I live in a basements suite. Nice and cool for the most part.

:cool:

Oh, it was 30C in my tank yesterday night around 8pm. 30C was the upper limit on my thermometer. I guess I need to get a new thermometer.

So it could have been higher then? I'd get a new thermometer for sure.

I've got one of those cheap stick-on the outside thermometers. I'm guessing that if it was off-the-scale, none of the digits would be coloured up. If the last number 30 was being lit up, does this mean its 30 or above 30? I'm guessing it was 30. Hm, I'm getting a new thermometer tonight to be sure.

Sam, you may be right about the digits not showing if it was over.

yup I know but using whole numbers in F is more accurate than using whole numbers in C.. thats what I ment.. oh and you must be having a cold wave at your house, I have 3 thermomitors all saying between 91.8 and 93.1. I may come over to cool down (oh this is at 5 PM and in the shade.. they were saying almost 34 degree C about 2 PM instead of the 32 degree C I have now :mrgreen:

On another note I added a new fan and made the day go cloudy by turning of the MH at 2pm today.. my temp is actualy cooling down now.

Steve

It's funny how the F and C don't translate to all things. Of course I'm old too.

I said something was a foot long once and my kids burst out laughing.....what the heck is a "foot" Mom?

This is my first year with all SW tanks downstairs. At least the FW upstairs needs no lights, so that should help a bit. I think I had to put frozen pop bottles in the 155g sump once last year. The way this summer is looking, not much to worry about. I always keep the heaters on and set to 80, so the tank doesn't drop too low overnight.

anyone ponder about DIY type deal of a dryer vent system leading hot MH canopy air out?

Does that make sense? lol heat has fried my brain today

For me, its because I grew up watching pro sports and collecting hockey cards that listed all of the players in feet and inches and pounds. I think even Canadian news still quite often talk in feet, inches, and pounds for height and weight. Even when buying wood from hardware stores, they talk about 1/2", 1/4" thickness etc.

im a young guy. metric is bogus :razz:

ever look at DIY plans from Austrailia or the like? 44cm x 24cm. 154mm MTF.. etc. Its like a whole language I dont understand :rolleyes: :lol:

with the lights and fans running, my tank is at 83.5. it's hot in here thanks to those lights. my ceiling fan is gonna be working overtime this summer.

i'm only 19 and i use a lot of fahrenheit. my height, weight... however i use metric for a lot of distances. where i work i do a lot of converting so i can do smaller sizes in both. [/u]

Emily;

Here's some info to help explain imperial units to your little one. Once you figure it out, maybe you can explain the logic behind it to me. My wife has her own similar units of length when we are on the road and she is assisting by reading maps. Her units of distance are in fingers. "Only 5 fingers and we are there"


"foot (ft or ')It may be an innovation of Henry I, who reigned from 1100 to 1135. Later in the 1100s a foot of modern length, the "foot of St. Paul's," was inscribed on the base of a column of St. Paul's Church in London, so that everyone could see the length of this new foot. From 1300, at least, to the present day there appears be little or no change in the length of the foot.

degree Fahrenheit (°F) a traditional unit of temperature still used customarily in the United States. The unit was defined by the German physicist Daniel G. Fahrenheit (1686-1736), who also invented the mercury thermometer. Fahrenheit set 0° at the coldest temperature he could conveniently achieve using an ice and salt mixture, and he intended to set 100° at the temperature of the human body. (He was off a little there; normal temperature for humans is between 98 °F and 99 °F.) On this scale, the freezing point of water (at normal sea level atmospheric pressure) turned out to be about 32 °F and the boiling point about 212 °F. Eventually the scale was precisely defined by these two temperatures. 1°F equals 5/9 °C, but in converting between scales we have to be careful to adjust the zero points as well. To convert a temperature in °F to the Celsius scale, we must first subtract 32° and then multiply by 5/9. In the other direction, to convert a temperature in °C to the Fahrenheit scale, we must first multiply by 9/5 and then add 32°. The Celsius scale is now used everywhere outside the United States, so only Americans need to remember these formulas."

This imperial units are for Cave people only :exclaim:

:lol:

My heaters are set for 81-82F. Yesterday tank was 86F when I got home at 10pm. That's on the high side but not lethal. Nonetheless, I reinstalled the acrylic lens in my MH fixture, optimized a household fan directed across the top and plugged into a timer (I love these things :mrgreen: ), and blocked off half of my huge sliding glass doors with cardboard. These suckers face SW and turn my place into a greenhouse on hot bright afternoons. Tonight, the tank barely hit 83F.

So if you have alot of window, using shutters, awnings, or carboard (yeah it looks like hell but fish are more important :smile: ) can help keep the heat away from the tank in the first place. These really need to be used on the outside, stopping the sunlight from refracting through the glass and transferring heat.

its almost 3am and i got home to a 92 degree tanks =(

When I was learning measure in school, we learned only Imperial. Later on in high school, they tried teaching us Metric. I will probably use imperial til the day I die. I only know that 20C is about 70F and that's it. :mrgreen:

ok I thought this might be a good time to show a product that I use and could be handy for you guys that don't know how hot your getting.

http://www.radioshack.ca/estore/Prod...log=RadioShack

this one is the step up from mine as it has humidity also. This might be handy for monituring room humidity also. The good thing about thease is that they have a memory of your lowest and highest temps, and humidity in this one also.

I have been using mine for over a year now and the probe is fine.

I am going to go buy this one myself as because of pour placement I have nocked mine into my sump twice and part of the display isn't working right. (good thing it is the indoor display part)

Steve

okay, with my tank being screwed up with the temperature, I have now lost my longhorn cowfish ( with no ill effects on the tank...yet ), my cleaner shrimp and my strawberry psuedochromis. Corals seem to be fine, for now. Elegance has now doubled in size after all this stuff, and the same goes for my mushrooms. I can't seem to find my arrow crab, but I did find a recent molted shell of his. The anemone crab survived and the olive tang, and my redtail diadema, and both of my clownfish, even though my small sebae was laying on his side this morning having problems breathing. The tank temperature has now been brought somewhat under control for now, it is at 86.6, not bad for 6pm.
I am crossing my fingers for the next few days

Whoa! Just in time...I just installed a new 10000btu AC in our livingroom.
I've completely reversed the photoperiod on all the tanks' light timers & placed a desk fan on max to blow across the lights.
Time for a little fan in the sump I think...God I can't wait for the day I get a chiller!
:onfire:

Re: So how is everyone's temp holding up?
 

Temp swings are a thing of the past for us now that we have AC :cool:

Good thing we have it too, because our sub-tropical seahorses require temps between 72 and 77 F.

my tank is at 86. doesn't bode well for someone who just set up their tank. and it's not even that hot out yet.

Those dam 400watter's eh :razz: :lol: :confused: :frown: :neutral: :sad:
As you can tell I don't really know what to think

In one of my home systems I ran a 4" fan directly into the water with the lights out most of the day, great way for reducing the temp, 86 to 82.

All of the snails, came right to the top of the tank.........

Has anyone else experienced this ?


Wendell

PS As for the fishroom, tanks are fine with 5 chillers, but the fishroom was 33 degrees today..............

Wendell, i had gone out and bought 3 fans yesterday andpointed them to the outside of the tank. I did notice all th snails were near the fans at the top of the tank too

Anyone know why the snails come to the top ?

Oxygen?

Coming out to fix the damn AC ??? :smile:

cause they want to get out of the hot water?? or maybe they want to cross a road or something??haha..
I do notice this though, my snails are always at the top of the water at night time, maybe it is a temperature difference

Looks like a cooler day here. My tank is 2 degrees (79F) colder than it normally is. Too many fans on it today :-)

Dawn heat wave...

I lost 4 colonies (2 yellow cap, 1 pink mill, 1 shao's coral) and endless amount of frags. Even my Xenia is not doing well.

My tank goes up to 90F yesterday. I usually keep my tank around 80F - 84F. I just bought a new fan from Canadian Tire yesterday and now the temp drops back to around 81F.

Another tips to further reduce temp is to turn off the actinic. Corals doesn't need the actinic to survive. For me, that's 220watt of tube, so it makes some different. I forgot about that until too late.

Hope everyone else is doing well.

Bongy

What seems very funny to me is that everyone seems so unprepared for the heat :cool: . I have been doing aquariums for a few years now atleast and am usualy not too worried about temp now since my first summer with aquariums. I donno, I just thought most ppl would be used to this by now :question:

Sorry to hear Bongy. Have you considered changing the time of day that you turn on your MH lights? Maybe have them turn on in the early morning around 4am and off by 12pm and then on again at 8pm-12:30 am. Or just go 9pm-11am (14 hours) or something like that. You can leave your PC lights on at the regular times. Would that work or would that be too disruptive to the corals?
