Bought two 5" DC fans.....Ran at full blast..No good..get down to 28Cel only.Seems like most heats are contributed by the pumps and lighting placed to close to the water surface.
Few days ago, I tried something really interesting on reducing the water temp.Did a diy "chiller" with a small 8"x6" radiator ..hooked up some hoses to a power head,a fan and used a digital therm. to monitor on a 2ft tank.Wow within 15min the temp dropped from 27.8-25.9..great unfortunately made a huge mess when i found out the radiator spitting out oil.... yukk!!
But what great "chiller" that almost cost nothing to build!!!

Hey Roadspike, what other LFS do you often visit for plants?? Anyone been to Ocean World Aq. in Kepong Ind Park, wonder what they got in stock??ok thanks
