What is your ambient water temperature?

[cannon_eer15]

Mine is 31 degrees! This is without any lighting to heat it up! Is anyone running their tank at around this temperature without fans?

[lyz77]

Mine is between 29.5 to 31 deg without fan! Better to keep yr temp below 27.5 if u r keeping coral!

[Altantis]

Some month can be more tha 31 if your window is closed & w/o fan when you return home after work...

Anyone experienced massive die-off when this happens?

My Nano Cube + 150W MH rose to 32ºC at one point (while cycling). So I quickly (not much choice really) bought a Teco RA240. Now temperature maintained at 26.5ºC - 28ºC. My LS seems happy... can't imagine them boiling in 32ºC water... surely die one.

If you are keeping fish only, then it's ok (I think). The fish tank at Reborn (2nd level) is always 33ºC. They keep some large fishes like angels there.

IMO high temperature not only affect your LS but a lot of other related conditions. Oxygen level for one is affected by temperature. I think a lot of other parameters are also temperature dependent. So, if you fishes died, not necessarily coz they are hot, but degraded water conditions in general... my 2 cents.

My water temperature hovered around 28 to 29 degrees when i 1st started my tank. Thats without chiller or fan. But with the current hot weather....it'll easily reach 31 or even 32 if i don't have a chiller. Thats gonna be too high for corals.

With the current weather, your tank can easily get up 31C... A few days back, i forgotten to put back my Fans when i was arranging some corals and it rose to 30C...

Luckily i noticed it and place it back... If not i guess the corals might be boiled liao...

Other months, the ambient temp is 28-29C without fans...

yes. 90% all coral die.

34 degree without lighting. 3 Pump running 24hrs.

reason. the chiller hose drop off and so happen that i oversea 3 days.

My wife don't know abt chiller. when i back, left afew fishes and alot dead fishes.

My wife scare to take those body out. MEAN every smelly too.....

Oh man! What a disaster... next time teach your wife what to do la... tell her, once she spotted dead fish in the tank... do the following steps 1, 2, 3... but again, more easily said than done.

yup yup, but not all died, only the doctor shrimp and forgot wat else

[d88p]

it is a hot day again

[ywng85]

Try to turn on ur lights at night lo.. Cooler at night though if u are using MH it does not help. Some more after eleven electricity bill cheaper. Hehe.. But of course if turn on at late night nobody would wanna see ur tank.

[d88p]

i didnt know theres such things as discounted rates after a certain hour..... are you sure? never heard of it before.

[blueheaven]

Remember this:

Most corals will start to expel zooxathellae once the temperatures are above 30 degrees

But from personal experience, I find that 27-28 degrees suit the corals quite well

Colder temperatures should also be avoided as the corals will be stressed

Hi

My temp is also around 31 degrees now with additional pumps added. Fishes are ok though, but i find inverts' lifespan not as long as when my temp is below 30 degrees...

Inverts and corals are much more sensitive to water temperature than fishes. 31 degrees in my humble opinion is suitable for a fish only tank, inverts and corals will not last long in that temperature range.

[d88p]

even if we feel hot, we cannot tahan right?

[jervismun]

Yalor... last night very hot... my tank 27ºC... my room 30ºC, lol... how I wish I'm my fishies instead... damn good live

LoL....on the aricon or fan? My fishes lead better lives than me too....

[colinsoon]

its been a well known fact my fishes are living much better lives then me... haiz.

[hammy]

mine can go up to 34degree celcius with one extrema, aquamedic PH2000 and seio 620

[tigershark]

i'mnot trying to be nasty but hope the reefers could be more responsible for their action.... if u wana keep coral, install a good and strong fan at least.... with good air vendalation (lower humidity to increase the evaporation) the water temp should be below 30 deg. A chiller is a better choice in long run.... chiller price drop a lot recently, a taiwanese brand new chiller could be pruchase below $500 easily....

IMO , the only downside of Ac fan is that they are too noisy and causes lotsa evaporation . but comsumption os electricity and cost is minimal

chiller is expensive which coast at least 300 SGD for a resun CL280 and absorb lotsa electricity. but it prevent excessive evaporation and more reliable.

i switch from a fan to chiller since then.

fan can cool to 27 degree on a good day

chiller can cool to 26 degree .

[Qxnviolet]

Hrmz, actually has anyone really caculated how much it takes to run a chiller monthly on the presumption it runs 24hrs a day? Im bad at electrical stuff....
