OK I REALLY HAVE TO ASK>? Y ON TEMPERATURES

[KING]

ok well this might be a dum thing to ask ,but every one says to keep ur tank from 75-78..but majority of coral reefs are found in temps of 80-89..dont even no if what im reading is right..but when my tank some times hits 83..i shut my light down..but do i really need to>?
o..i googled reef tank temperatures...how hight is too hight..saltaqurium.about writes this..:what_smile:

I looked around for average temperatures of reefs in the world and the take away temperature spread was 68-82f.

You may, IMO, see higher temps in areas and hardy coral may do well due to the gradual increase. In other words, the temperature doesn't rise over night. It takes a few days to a few weeks.

In your aquarium it happens over hours. Too much if a variance over too short of a time.

I've had my temp shoot to 84 or 85 when I was first starting out. I only had a couple coral pieces at the time, hairy green shrooms and Texas trash pallies. They fared well, but I lost an eel and two of my chromis.

Turning the light out is a good idea at that temp. You can also run a fan over your sump for heat dissipation. You will have to add more water topoff, but generally speaking that's the best, and cheapest, way to help regulate water temp.

The added heat, and the lights, cause the zooanthella kick into overdrive which causes them to release toxins. The coral will then expel the algae, thus the bleaching effect. A coral colony can rebuild it's zooanthella colony from the remaining algae if the conditions are good, but they are also prone to infections in their naked state.

Hope this helps.

From my experience once my tank started getting over 83 things would start bleaching if it stayed that way also anywhere over 85 and coral started closing up and not looking very good, on the cold side ive had my tems down in the 70 range for a week or two at a time and didnt notice much during that period of time.

The seahorse tanks are kept below 75 degrees - ideally at around 71. Bacterial growth increases at higher temps and it's a contributor to problems in seahorses so lower temps are better.

The reef tank is kept at 79-80 degrees

fwiw, my reef tank has been running 70-74 F for the last month or so and things are doing fine. i have also had an sps reef tank run consistently warm (83 F). most corals did fine, but the sps coloration was not as good at temps higher than 80 F. i think, like allan said, the key is that the short term change is minimal.

Where your animals came from determine the ideal temperature.

In my experience, too low of a temp had little effect. Too high of a temp was deadly.

allan...thanks with all the info..an every one on the feed back..sometimes looking up stuff goes south for me..lol or i have to read 3 or 4 pages of junk just to get what i was asking for..after i posted 350gt slammed my phone with info..lol
oo how yall feel about the old ice a milk jug an put that in the sump trick>>?? lol

[allan]

I keep an ice jug in the freezer for emergencies... but there's a huge chasm between that method of keeping temps within range and using it as an emergency. Not familiar with your light set up, but a lot of MH folks seem to run their lamps for about six hours and the rest of the time they run VHO or T5s. I run my MH for 12 hours, no canopy, fan in the room and a chiller that is rarely on. We keep the house temperature at around 75 during the winter and 72-73 in the summer. If my temps start to swing up, and to lesson the responsibility of the chiller to maintain temps, I run a fan during the same time that I run the lamps. The fan really works well, and it's a KISS method to be sure. I want to get one of them controllers so that I can have the temperature readings control when the fan turns on and off, but it's a little out of my budget. But the ice jug... definitely for emergency use only. Unless you're always at the house and enjoy the extra work. :)

As I've said often, fish can move when the temp gets too hot. Corals, not so much. We've been on reefs in the upper 80s. The corals don't like it, but it doesn't kill them. The fish hate it.

[Europhyllia]

I have LED lights on all of my setups and fans on the seahorse set ups. They are connected to the reefkeeper. when the temps go above 74 degrees the fans kick on. Makes for noticable evaporation but keeps my temps within a 2 degrees range always.
I can't imagine anybody doing the ice jug thing continuously?

One other thing to think about as well is that the temperatures being a little high is as long as it is stable. Huge swings tend to cause more problems than a tank that stays at 80.

+1 Stability is the key

A few years ago we went to Tahiti for a few weeks, and the water temperature was a consistant 80-81, and the reefs were SPS dominated. I think it has a lot to do with where your corals are from, and understanding this when you choose your specimens. It is truly amazing how adaptable the creatures are..... My experience was when my tank was hotter with 3-400s (83-85) my corals grew much faster, and were very hardy. However this might be due to the light intensity rather than the temperature. Hotter temps will increase coral metabolism to a point... So I would burn through more trace elements quicker during warmer months. From my experience the key to higher temps is feed the system more to support it, and keep it nutrient rich.

[/QUOTE]

I didnt slam your phone but if you would listen to me from the beginning, alot of issues you have had wouldnt have happened..... Just saying.


I was fortunate to have Rubens brain to pick while starting up but I listened for the most part. If you would have brought me that canopy before rushing to put it all together, we could have had it ventilated better. But its a common mistake to rush into things when you first start, I am glad I didnt and even then I would have done a few things different....

[350gt]

AND IF YOU WANT SOME REAL ADVICE!!!!!!!!!!!!........


stop buying stuff till you address those heat issues......... with all the money you have dropped on corals, there is no reason you should be having any type of issues.....:bigsmile:

[KING]

NNNAAAAAA..IM GOOD AN MY TANK BEING AN 80 IS NOT AN ISSUE WITH ME..SO NOT REAL ADVICE ..OR JUST MAYBE I DIDNT MAKE MY SELF CLEAR... I WAS JUST ASKING ABOUT SOMETHING I READ..NOT THAT ITS SOMETHING IM GOING OFF OF..BUT THANKS ABOUT THINKING AN CARING ABOUT WUT I SPEND MONEY ON..AN U SHOULD NO AS 1 IN THIS HOBBY FOR A YR PLUS..NO MATTER WHAT UR GOING TO HAVE TO SPEND MONEY AN MISTAKES ARE MADE...(( EVEN WITH ALL THE ADVICE AND INFO )) :shades:...
TANKS WILL CRASH,CORALS WILL BEACH,AN FISH WILL DIE,,THATS ALL PART OF THIS HOBBY...
PS:HOPE NO 1 IS OFFENDED ..JUST MY 2CENTS

[350gt]

So not real advice? If you are not having heat issues, why you having to put ice in your sump? Or having to constantly maintain the tank to make sure it doesn't overheat? Why are you wanting fans in your canopy?Why you wanting to convert to LEDs to reduce heat?


Sorry but none of my corals have never bleached and I have never had a tank crash.... Both of those are human error...

[350gt]

And I don't care what you spend your money on...... But when someone asks for advice then just goes completely against what you said, it is bothersome..... You ever see that dude with the 22's thinking he looks fly when his car is a POS? Just saying fix the car, then get the bling.... But to each there own..... I would rather have a properly running car than stupid wheels....

[350gt]

And I have yet to make a mistake in this hobby cause I was patient and listen to the advice that was given to me by ruben, JT and a few others....
