danpee Posted January 12, 2009 Share Posted January 12, 2009 has anyone tried it ? any good ? as far as can see its a computer fan on a heat sink attached to an alluminium rod ? can any one add to that ? cheers Link to comment
Phixion Posted January 12, 2009 Share Posted January 12, 2009 They work, several people on here have/do use them with good results. They are best used with a temp controller though such as a Ranco or better yet, a reef controller like an ACjr or ReefKeeper. or the poorman's method is to put on on a timer to come on either during your light cycle, or several times through the day. Good luck! Link to comment
danpee Posted January 12, 2009 Author Share Posted January 12, 2009 they look simple enough to do a DIY one, what do you think the probe that sits in the water is made from ? also what metal do they use for the little rod that keeps the impeller straight in power heads ? does anybody think a glass rod would work ?

Glass might be iffy I'd think. Some use ceramic however, I have seen steel before though or at least something that eventually rusts. And others use titanium. As for the probe, I believe the housing that contacts the water is plastic. Really you don't want any metal in the tank at least physically contacting the water. Way too much risk of contamination and/or leaching of unwanted things into the tank. Link to comment
hcsceo Posted January 12, 2009 Share Posted January 12, 2009 Glass won't work well as it isn't a thermal conductor. You can go to nanotuners and get a waterblock and peltier and add it to your own heat sink and you are good to go. Steve Link to comment

Steve I believe the OP was implying about using glass for the center rod of an impeller blade, that's how I read their question as at least... Link to comment
bonsai reefer Posted January 13, 2009 Share Posted January 13, 2009 I had 2 on my 12 with a 70w mh they did not do much but run my electric bill up They were constantly running but not doing much cooling Link to comment
Marteen Posted January 13, 2009 Share Posted January 13, 2009 It's a little more involved to build a chiller than slapping a impeller on a heatsink. Link to comment
