Very few people need chillers. They are necessary if your temperatures are getting out of control. But there are other, cheaper, more effective ways to try to cool a tank before you should resort to a chiller.
I try to tell people do not setup a tank in a warm place to begin with. Direct sunlight, heating vents and rooms without air-conditioning can cause over-heating. A $100 A/C window unit my solve your problem and cost less then a small $300 chiller.
I use a fan in the summer only. When the room gets to 85F I turn on the central A/C.
Small clip on fans from Walmart blowing across the top of your tank and/or sump can work wonders for tank cooling!! Unless you plan to keep cool/cold water species, like Maine lobsters, you should not need a chiller.
sounds good, my tank is going in a room with A/C, so summers will be fine. And, I'm Canadian, so the rest of the year shouldnt be a problem! :bounce: I'll have to keep the heater working full steam in the igloo!! :mrgreen:
