Water Temp ?

I have a fish only tank :

What temp is too high to keep salt water fish ?
Naso Tang
Blue Hippo Tank
Tomato Clown
Fox Face
Dog Face

Is it ok for the temp to spike to what ?

I know what a suitable temp is 79deg .

I had allways keept fresh fish ATF/Piranha/Vampire tetra/Wolf Fish exc....
Monsters . It was ok with my fresh water for temp to spike in the uper 80's with good surface tention . Is that also the case with my salt water fish ?

 

Most coral reefs, from where our livestock is collected, seem to average about 82 degrees or so. Even though this is FOWL, the fish still come from the same oceans. My tank ranges from about 77-85 degrees. I try to allow it to vary a bit to prevent temperature acclimation. I have inverts though, fish are generally more tolerant.

 

Mine usually stays around 78*. It may drop down to 77* at night due to cold MT winters or spike to 79* when MT winters warms up LOL My inverts seem to be doing well and my fish are plump and happy. Noel (pistol shrimp) seems to be doing well too since I found a NEW burrow dug today because there is ANOTHER sand pile in my tank *slaps forehead*

 

My water stays at 86 and I want to get it down to 79-80 . I did not have this problem untill I put new return pumps in that are more than ample to turn the tank over , I guess its a combo of -new lighting- a- tight fit canopy-and the -pumps running warmer- than the old one's due to there size 1400gphx2on a 180 + 2-powerheads at 1200gph

I will try two fans (of some type) in the top of my canopy facing stright down at the water . Another thing I will do is uncover my Sump , I insulated it to be sound proof (it's rite behind my couch) .

If I do not get good resault I will make a Chiller .

Ill put some pic,s and feed back on my resualts on this thread

 

Some reefs do get that warm, or even warmer during certain months. If everything is acclimated to it, it shouldn't be an issue. The real concern would be if there is a heat wave and the temp rises for a while, as you are already on the higher side of the acceptable limit. Fans are cheap and should be able to drop the temp several degrees.

 

i think any temp over 82 is pushing it. but stability is key as with all things.

 

82 Man most of the worlds reefs must be dead

There is some debate about higher temps in an aquarium due to metabolism and O2 levels, however, diferences in O2 levels, even with large chages are very nominal, only a few percent. Also, recently fish and inverts have been show to acclimate to higher temps and their metabolism reverts to normal; at least within a reasonable temp range.

As for normal temp ranges, Dr. Shimek gives some useful data here.
Aquarium Frontiers On-Line: November 1997: Feature

Also re: stability, as described here, there is variability in a reef. Reefs.org: Where Reefkeeping Begins on the Internet - Temperature on the Reef

More interestingly, more recently it research has been showing that both fish and inverts have can acclimate to temperature variation.

With inverts, especially, there even seems to be a benefit to allowing them to acclimate to temperature variations. Research, such as Mcclanahan 2007 have found that corals exposed to greater variation of temperature, are more likely to survive prolonged extreme temperature swings.

This also seems to be the case in aquariums too. I have found that people who keep their tanks at constant temperatures, seem to be more likely to report death during equipment failure induced temperature swings, than people whos aquariums vary normally. I wouldn't be too concerned if my tank reach 90 degrees for a day, but I've heard endless accounts of people with chillers loosing all their livestock when their tank reaches 90. Something to consider...

 

m2434 I think you seem to know the dig on the topic . I will go with what you say ,

 

keep in mind there is a big difference between the ocean and a glass box of water.
