water temperature, thermometer

[Hazel]

Hi,
My new planted tank (2ft --- 20 gallons)has 2 PL lights.
The temperature on the thermometer is always at 29-30 degrees celcius, whether it is daytime or night time, or whether lights on or off. Should i get a chiller or a fan to lower the temperature? Can there be something wrong with my thermometer? Which brand is more reliable? The normal type or digital type?

Thanks.

I use Sera thermometer. It specified that the thermometer is accurate to 0.?#176;C (can't remember what the exact accuracy, but it is pretty accurate for aquarium application).

The temp of your tank sounds about rite..... temp may vary between lites on/off. Check at that time if you want to confirm the thermoter or you could put in something warmer/cooler to see if it changes.

IMO, you don't need a chiller for your 20g tank. A fan would do fine.

Mine's 20 gallon too. Using 2 fans now. Temp is hovering around 26 - 28 degrees. Sometimes even go to 25 degrees. Not bad for a cheapo fan solution [:]

I believe the Sera thermometer is digital? Any lfs carrying it and what is the estimated price?

It is not a digital thermometer. Just a few $, can't remember how much it cost exactly.

Some of those digital ones can be quite far out... like almost 1°C. But only hear pple say, no actual experience with them.
