Best Reef Temp!!!

[Cibo]

Whats the best temp for a reef. I know some who has a JBJ with the JBJ MH hood The runs in low 80's I feel that too hot? this tank looks like bad it has a dead look to everything his first problem was to high salt had him get it in check now the only think I can think is temp. He said that all the numbers are ot 0, the the coral does not open up I gave him some zoos they look small and not opened up, in my tank they look great. I keep mine at 78drg.

Is there a problem with the jbj mh hoods anyone have coral doing well with that setup? It seem like a small closed in tank for a 150 mh. is the a mod that will make it run cooler?

thanks

I prefer 75 degrees As for your friends issues I'm not sure. If he is above 82 degrees consistently that could cause a problem.

Do coral like the lower temp(75) what the benfit to 75

for my tank76-77 degrees is the best I see more polyps extended at this temp

75 degrees is not a bad temp. But everyone will have different medium temps but I agree with Domboski 82 is too high for a constant temp, it can reach it but not stay there for hours. I personally like to see mine at 79 now. But at one time I liked 76 just in case something failed and the heat rose it would take longer for the water temp to raise.

77 ... I did notice some awesome polyp extension when it went down to 73 though ... I was doing some work on the tank late ... fell asleep and forgot to plug back in the heater of all things ... everything looked GREAT!!!

80 on average

as a previous owner of a JBJ 150mh tank i am sure his temps are higher than low 80's more like mid to high.... the fix is either make a stand for the light to stand off the tank about 4" and put 4 computer fans in the back to blow across the top of the water, get a chiller, or order the upgrade fans from nanotuners....
my temp is 79.5-80.8

mine stays 77-79 via chiller

My old tanks were at 78-80 my new one will be in the 76-77 range.

77.8 to 78.2 is my syeady range for the last 4 years.. Kept by ac, fan and heater controlled by Rk2 in the beginning, now AC3 pro.

i got mine on average from 76-80 i notice when its 79-80 everything looks stressed but when its 76-78 everything is fine

 

[Cibo]

after reading the responses I droped my chill to 76 so I guess it will run now 75.5 to 76.5 ?

All of my tanks have crossed the 80 mark with no issues, my nano has even crossed 83. IMO allowing warmer temps for seasonal changes is normal and healthier for our systems, locking temps at a specific degree will only stress our animals more when they do fluctuate. Take your average reefer who keeps the house warm at say 78, the system at 76 during the summer has a chiller failure and climbs to 82, a 6 degree swing and big stress, the system at 79 same scenario hitting 82 is only 3 degrees and less stressful.

Just to give you some idea, average water temps at some locations...

My Tank with the MH's on gets to 81-82 without 79-80.

When i was researching the lighting for my 120, MH lamps should be 12 to 15" above the water surface or tank overheating would occur. Not sure if that is the case here. Another recommendation was to install a fan between the fixture and water surface setup to blow across the tank to facilitate evaporative cooling, I don't think the fans in the fixture provide this and are mainly to cool themselves. Just my 2 cents

79.7-80. I like minimal fluctuation. Higher temp = less evaporation from fans cooling aquarium. Doesn't cost that much to heat a 75 in the winter, so i leave it there year round.

77-78 with a chiller.Closed systems need it at least mine does.
