Certainly less costly than a water chiller. Simpler, too.
Hi all,
khyberkitsune a quick question, as the little peltier cooler are about $5.00 to $10.00 or so each from ebay, how many would you need for a 55 gallon reservoir?
What would be the correct wattage? I find wattage between 91.2 and 250. There seem to be a lot of choices for me to screw up on, so as not to irritate the wife I'd like to get it right the first time.
I have looked and can't really find an answer to this and don't want to have to experiment too much.

BTW, I'm running a 55 gallon ebb and grow.

Thanks as always,
Buz :smokin:
Buzkill Reviewed by Buzkill on . Cooling the rez. temp Another silly question, I think: With a small (5 gal) rez. it seems silly to spend big bucks on a water chiller. Only really seem to 'need' it when the temps outdoors get near 90, since everyone in the area turns on the AC and power becomes unstable. The question becomes: is it OK, or even worth it, to fill a clean plastic bag (sealable) with ice cubes and place it in the rez. to help lower temp a few degrees? Looking for a drop of maybe 9 degrees or so. Thanks yet again, mrmcr2 Rating: 5
