What is your ambient water temperature?

[fakrul]

Just wondering if I should buy a fan. my water temp without fan is 28-29. should i still buy a fan?

I think you may gate more info from

So you may go to these sites for yourself.

Without fan and with lights on under the hood, my water can goes up to 31. The Christmas moss turned black and start falling off at this temp.

Ever since I installed 2 computer fan, one blowing at the sump at an angle and the other as an exhaust fan for the cabinet where the sump is in. Without air-con it hovers around 28 and never exceed 29. With air-con turned on, it ranges around 25 - 27 depending on how heated the water in the tank is.
During raining weather, it drop below 25 with air-con running. I also open the front and back of the hood lid for better circulation to reduce trapped heat from the light.
The fan are on the same timer as the lights and runs only when lights are on in the day. Average temp in the day without light is around 28.5.

Very tempted to get chiller initially but after reading this thread, i don't think it is really necessary unless I decided to keep shrimp right?

25 is best for temp

[lizhien]

My temp averages 26 degrees.. With air-con in the room it can go to 22 degrees.. I have a small 1 ft tank in my room with tetras and corys. But the evaporation rate is really high.. Need to top up 1.5L of water every 2 days. Previously without the fan I could go by with 1L top up every week.

Current temp is 29 average. No fans

[chumzhujun]

My increase to 29.........

[vannel]

Ambient is about 28-29deg. With a Dymax fan on during the day, temp maintains at 28deg. At night, with air-con, 26deg. Air-con + Dymax fan is about 22-23deg.

Hood on 4 ft with 2 out of 3 lights on and no cooling fan - 32.5 degC, highest 32.6 degC.

Perhaps time to switch to LED lights and DIY some vents for my tank hood.

You want vent fans? Free

Very powerful.

My tank is a SunSun tank, I don't think those fans will fit.I have to find a way to reduce the water temperature, without having to modify the hood too much. Thanks for the offer however Felix.

Even with a fan on my 6G tank, I am running around 28-29 on most days. Am doing some mod to fit a iceprobe into a Shibuya 301 filter with help from the chap at GC. Will report back how much I can reduce my temp to. Just want to reach 26 will do.

my 1 feet tank average about 29+ deg c. Never lower than 29 deg.I intend to get a dymax cooling fan windy W-4 but I'm sure if it will be able to bring the temp down to a temperature suitable to keep shrimps.

You mean currently? It's the hot season it might reach low of 28 depending on environment.

What shrimp you are looking at? Hopefully not high grade ones. 1 footer will have easily affected parameters.

I'm keeping cherries, Malayan & Yamato in hot tanks. 29-30d average.
IMHO, if indoors can hit 30. Nothing higher then firered.

Yes currently it always in the region of 29 deg. I'm thinking of keeping sakura or maybe crs. So a fan will only lower the temp by around 1 deg?

I change my water weekly. Would these parameters still be a problem?

[felix_fx2]

Doubt crs will survive long.
Cooling with fan, you need more surface x air contact to cool. Since a small tank limited surface area for the fan to blow.

There are numerous post about small tank keeping crs with only fan cooled. So the details you can dig then out. (I'm just making you search more hehe)

The short reply: crs maybe can but even if can barely survive will not look nice.

[dc20]

Alright then might just keep sakura instead haha. Thanks.

[newlife]

Erm..maybe you could check out with bro Spid how he manage to keep and breed those beauty shrimp with out chiller.

HELP! My tank is like 32-33 degrees C with lights on... how am I supposed to keep plants or fish or even shrimp (RCS needs ~ 27 C) inside?!
I heard installing fans would only decrease by 1/2 deg which is still high! howhowhow...

4gal Tank
2 x 6W GE fluorescent tube around 4-6cm from water surface in an aquarium hood
submersible powerhead filter

A picture of your tank would be good. If your tank is hooded, that's most likely why the tank is getting a high temperature.

My temperature varies.
3ft in hall - 29c with a Gex L fan blowing 24/7
2ft in hall - 26c with a Dymax 8w blowing 24/7
3ft in kitchen - 32c with hood covered & no fan
