My Chistmas grow well at 28 degree too.Originally Posted by EKI
I had fan 24/7 too...... seem well ...hope it help
one thing i find bad about using a cooler fan is the evaporation. Every week I have to top up about half a pail full of water to maintain the water level. But still, the cost difference between fan and chiller is too huge for me to be willing to invest in a chiller.
According to the Aquarium Plants Manual by Ines Scheurmann, the following
will grow at water temperatures up to 86 deg F (30 deg C):
Hygrophila polysperma
Aponogeton crispus
Cryptocoryne wendtii
Cryptocoryne willisii
Echinodorus bleheri
Vallisneria spiralis (corkscrew)
Alternanthera reineckii
Ludwigia repens
Myriophyllum aquaticum
Rotala macrandra
Rotala rotundifolia
Ceratopteris thalictroides
Riccia fluitans
Java Moss
I'd certainly extend 90% or more species to about 35-40C.
Why?
My temps get that high here in the summer.
I know of no plant that does not do very well at 30C other than a few Aponogeton and then that's only over the long term after flowering.
This is through direct experience and about 300 species or so I've grown
Metabolism and CO2 demand goes way up as you go from 20 C to 30 C.
So things go faster and you need more to keep up.
At about 40C things start to break down.
But a few species will still grow.

Ambient is over 29 sometimes my aircon remote shows 31.
I have a TECO Chiller that brings it down to 26.5 ~ 27.5 that is the tank at home.
The one at work is mostly under an aircon so it goes as low as 24 which is why I think that tank is doing very well.
- Always Exceptions to the Rules -
- Explain yourself thoroughly in the forums not just state the obvious -
- Overkill is the best killing! -
My tank is 27-28 with 2 pcs of 60mm DIY fans. Without the fans, temperature rise to 29-30. And by the way, I arranged them to suck air out from tank instead of blowing air into the tank. Is this the right way ?
fan is cheap and it save alot of electricity, just that evaporation is much faster.
my 2 cents
Keeping Tank Cool
One can avoid fan and still keep water temperature below 30 degrees Celius by using lamps that has transparent plastic shade under them which greatly reduce heated air around lamps from reaching the water.
With the shade, the heated air is being absorbed by its' casing and then dissipate to the air above the casing. This creates convection where heated air above the lamp rises which in turn draw cooler ambient air to the water.
In this way, water is limited to receives heat through radiation.
Lost of light is insignificant so long the transparent plastic is kept clean.
For example:

BTW, through measurement of T5 lights using a PAR meter, we have found that you really do not need much light. This means less cost initially, and less electric cost, but....it also means much less heat generated.
1.5 W/gal is a typical amount used to grow virtually any plant.
2-2.5 w/gal I'd consider high light.

Resistance is futile, you will be administrated!

What do you recommend for ambient temperatures from 29 to 33 C? How much more should we dose for CO2 and fertilisers?
Vincent - AQ is for everyone, but not for 'u' and 'mi'.
Why use punctuation? See what a difference it makes:A woman, without her man, is nothing.
A woman: without her, man is nothing.
My tank's temperature without a fan/chiller is 30-31 °C. Plants seem to be fine except for my 2 crypts. Nothing expensive or wild, but the rest seem to be fine. I think it's the hood that is keeping the heat in. On cool days it drops to below 30 °C but not much lower.
In any case, nothing's dead yet and my swordplant is growing really huge, so I'm fine for now.
Fish.. Simply Irresistable
Back to Killies... slowly.
I guess it all boils down to the type of plants we intend to keep.IMHO.
Current temp of my 3ft is at 26.9C. Day time can go up to 28C. I controlled a lot on water flow, connecting a tube with many holes punched in. The tube is located near to water surface but it disperse the water evenly from back to front. Thus creating some very light constant flow there. Fish are doing fine, especially the flying zebra danios, zig zag the tank all the time.
Will be experimenting the DIY Solar powered Fan once the new tank is up. =) Good luck to me, hopefully no learning curve there, don't have to pay tuition fee.

NB: DIY Solar Panel do not work with Tank lights, hence this experiement has been taken off my current tank but will be deployed elsewhere. Solar Panel response to Sunlight, depending on the type of panel you use. You can drop by Sim Lim Square (Singapore) B Floor to find out more.

29% is my usual temp....
29 to 30, my area is damm hot.. sad
Mine is 28 ...
25.5-27 Degree Celsius
I managed to get the fans pictures.
I attached 3 pics here, one pic shows the inside view of the woodcase where the fans attached, one pic shows outside view (there's a hole on the back of each fan to blow out hot air, I guess that's the purpose why my father made holes there, actually I don't have very good knowledge about airflow ),
the last pic is the front view of the whole tank.

hi kenzai29 to 30
so how do u deal with the temp? any good method to cool it down beside getting a chiller) haha i using 2 fan : 1 at side of the lamp 1 at the centre..still temp read 29 - 30........
So, what is the good temp. for mosses? It depends on type of mosses. From my experience, Java moss is quite hardy, 28-30C is alright for them. But for others like erect, christmas and taiwan, they grow best when setting my chiller to 25C. I have consulted Boon Keng's Bioplast where they have very nice moss tanks display, they set the temp. to 25C. In Simei's Pet Safari which they have a very nice willow moss tank, I do check with the guy, they telling me the room temp is around 26C+-. So I believe 25C is good for most kind of mosses.
