I have done the ice bottles, tubing, and etc. and nothing compares or even comes close to the iceprobe and lowes five gallon cooler. It takes roughly 10 minutes to set up, remove the drain from the cooler expand the hole to fit the iceprobe through then connect a thermostat and your on auto pilot from now on, no more worrying about temps...ever. It runs about 5 to 7 hours a day sometimes more sometimes less at 50 watts. In the middle of summer temps stay at 68F even when the temps reach 95F+. I made a homemade iceprobe for $25 bucks, you can get all your parts on ebay or google shopping. The homemade one i made even works better because i can control the amount of power. The iceprobes do not have any moving parts besides the fan and have a lifespan of over 100,000 hours. They are very cheap to run $1.27 during the hottest month and if you have a larger reservoir such as a ten gallon or more you can add two probes. Ive seen one probe work on a ten gallon system.
