i need to take my tank temp down a couple degrees. aside from a chiller what else can be done? i already have a fan on the sump and its at 83.1f please help! ill go to walmart n do what i gotta do after a couple of replies thanks!
 
are you talking about a perm. help I'm guessing? Go to Menards or Home Depot and get the small fan to put in the canopy if you have one and face it across the water and your lights. You can buy a clip on one that will clip on your trim of your tank or a screw style one to mount in a canopy. That will reduce the temp. dramatically and is way cheaper than a chiller. Cost is about $15 or less for these and walmart does not carry them.

I have it setup in my canopy and it works great. You can take a look under my thread on here I just posted and will see it thru the pictures that are in the 75G Reef Ready new canopy and doors thread I just posted in reef discussions

83.1 is not deadly. Since you have a fan on the sump. I assume you turned the lights off. If you even take a large room fan and blow it up from the ground to the top of tank you can drop it that way also. My temp has hit 86 with no ill affect. Good luck. Is this a rare temp thing??
 
I use two small clip on fans to blow across the top of my tank. I have an Apex controller turn them on at 80.3 and off at 80.0. Works great unless the room temp gets above 80 or so.

The other thing to consider is your lighting. Even T5s will heat the water considerably. Try turning your lights off to cool the tank.
 
yea my dad decided to turn off the ac now sooooo yea temp is my room is hot now :/

Wow ur tank go to 86 n nothing happened?

just an idea what if i aimed to fans at the sump i dnt think i have space on rim of my tank to clip anything on
 
That will help but blowing over the tank is best. I tried a large fan over the sump because I didn't want ugly fans clipped to the DT. Didn't cool the tank enough for me since there is limited airflow under my stand.
 
83 Isn't bad as long as the temp does not fluctuate dramatically. My tank can go from 80 and as high as 87. No effects. Most coral and fish are tropic. You can look it up, most of the things in our tank are use to water in the 82-85 range during the day during the summer months. There is no reason to keep a tank at 78 at ALL TIMES. This does not happen in the wild where most our creatures are from anyways. Fluctuation is OK. Anything above 87 would be cause for alarm.
 
True. i can attest to temp paranoia. i live in the tropics and my tank temp does not go down below 82F. Wet season temp on my tank is 82-84F, summers are almost 86F sometimes. SPS dominated mixed reef tank.

Also True, fan across the DT is much more efficient that across the sump. Be ready for ridiculous amount of top-off though.
 
Just a thought....
The higher you run your tank temp, the less oxygen the water can hold. So it becomes a more critical path you are on - especially above about 82F.

If it is possible to bring the temp down to 80- or a bit lower- say 77 to 78, you will find it easier to manage. Ex: Algaes grow much slower below 80F.If you have an algae out break, lowering the temp will assist in dealing with it. As well - we do not keep "minaiture oceans" in our glass boxes, as much as we like to think that. Regardless of the ocean temp, we cannot duplicate the reef envirement indoors. We crowd animals of all kinds perhaps 1000's of times greater density than ever in the ocean. We cannot imitate the oceans ability to pass clean water over a reef one time, continuously forever. We do have only begun to understand the nutrient sink potentials of all the "non-reef" areas, and how they support life directly on the reef..... So, there are some other things to consider about temp. And temp. is an important part of the accuracy/influence of some tests we perform on our aquaria.

Just sayin......

If temperature causes you oxygenation problems, you've got much bigger issues than just the temperature. Throughout the range of natural reef temperatures (76-86) oxygen saturation is many times the critical [O2] for any reef fish. The effect of temperature on saturation throughout that range is minimal. All else being equal, in your 60 gallon tank, the difference in available oxygen at 86 compared to 78 is equivalent to the amount of oxygen used by a single clownfish in about 90 seconds.

Temperature can increase metabolism as well, but in eurythermal animals like the ones we keep, the difference tends to be small to non-existent over the range they're acclimatized. That is precisely what's seen in the few corals that have been tested and what I'm finding in my work with clownfish. Although there is little other work specifically with reef fish, temp independent respiration rates are common if not dominant among other subtropical/ tropical eurythermal species. In the cases where respiration is temp dependent, the increase tends to be about ~15% or so across the range of acclimatization.

For all intents and purposes hobbyists can ignore the effects of temperature on oxygenation.

Also, while there is a grain of truth to algae growing slight faster at higher temperatures, again the effect is minimal across the range of reef temp. You would be hard pressed to find anybody who has seen a measurable difference in algal growth rates. Over the course of 8 years, algae was certainly never any more of a problem in my tank during the summer when the temp regularly hit 86 than it was when the tank maxed out at 80 during the winter. Regardless of the temperature, algae still won't grow without excess nutrients anyway, so if you fix the actual nutrient issue there will be no problem regardless of the temperature.

Totally agree, couldn't have said it better myself.
