Cooling without a chiller.

[TinFury]

Is there any way to cool a tank and keep the temprature stable without a chiller?

I just leave the air conditioner on all summer.

I don't have an air conditioner. I live in Jamaica and most houses here don't have central AC.

In that case, I don't think you have much choice but to hook up a chiller

I saw a DIY chiller mod...I'll have to find it...but it used PVC with a rod of titanium in the center of it.

The PVC was sealed and i guess the titanium would constantly cool the water? Id go with the chiller though...definately more effective

Stable is the key word, isn't it?

Without a chiller of some sort, you are limited to evaporative cooling. Fans in the hood and the sump can help, but may not do enough on a hot humid day.

granted my buddy of mine really did a number to his home fridge. but he ran a pump from the sump to the fridge whit a ball valve to control flow. a hose goes threw the side of the fridge and runs back and forth allong the back of the fridge and comes out and back into the sump. although after useing the make shift chiller its a pain in the rear to up keep he says. he is constantly messing with it to keep it clean. really not worth the hassel. having a chiller is much better. i would not recomend doing it like this but if nothing else will do and i MEAN NOTHING. personally i just have watter bottles filled with RO frozen i flot in the top of my tank to help keep it cool. it works for a couple of degrees and i have enough circulation not to worry about cold spots in my tank and if a watter bottle leaks no biggie since i used the RO water. i guess you could put them in your sump too. but there is a couple of ideas that (i would froget about the hose in the fridge idea personally) well the ice bottles works for my tank, for now. im saving up to get a decent chiller.

Well, you can always use fans. That will cause a lot of evaporation but it should cool you tank somewhat. What is the average temp in the house? Fans can only do so much

Yo I found the coolest thing. It's dangerous but I think I'm going to try and build it. !!!!!!!!!!!!!!!!!!!!! Heres the link. AC without power.

Use a fan! They work are energy efficient and cheap to buy IMO! I have alot of success using fans to cool my water, though you will be adding alot of fresh water due to the fast rate of evaporation!
