So in the end it was cheaper to get a real chiller. It takes a Mag 5 to run though so you would need to run that water off the main tank somehow. Maybe a over the top drain and sump.

Thinking is cheap. Fortunately the closest LFS is 1 1/2 hours away.

Yeah I have a 150W hallide and I experience a similar temperature range. Thanks for the insight on the probe.

Until now I have been storing top-off water in the cabinet. Removing those bottles gives me a shelf I can dedicate to a chiller if necessary this summer. My carbon foot print is getting larger daily!

Now I really am going for that beer!
