tank temp again

[lotsofloo]

should i get another fan or another better power head.the weird thing is that when i off my pump,the tank temp decreases but when i on it the tank temp decreases.could your kindly advise me on how to lower it.does my tank temp drop because of water movement? thinking of gettin a better fan + a tunze nano strean

ehh... ur tank is small is it? i assume u mean when you off your wavemaker, temp decrease? that's possible as wavemaker generates heat... unless you get Vortech, where the motor is outside the tank...

Which power head are you using? Some cheap power heads produce a lot of heat and in a nano tank this can raise the temp of your tank by 1-2 degC. You can use the 25w clip on fans sold at some of the shops. These fans can cool down your tank temp easily by 2-3 degC and are better than using the computer fans or those small ones that you can buy at most LFS. The flip side of these fans is that your evaporation rate will increase a lot and you will end up having to top up water daily.

Tunze nano stream would be a good choice for a nano tank.
