Re: [APD] Canopy Cooling

Or piece of old bicycle tire inner tube, which is to
insulation what duct tape is to, well, to jsut about
everything ;-)

My favored method of cooling, when I have the option, is to
have a well-ventilated hood -- lots of opening for passive
airflow. It's almost impossible to hear passive airflow and
there are no mechanical parts to wear ;-) . Plusm it can be
quite effective. Here's an example, I replaced a hood on a
29 g. that was cooled with a 3" fan -- the hood had
openings at either end the diameter of the 3" fan. I
replaced that hood with one that I made similar to ones
that AHS sells (give or take a few structural
modifications), with the ample vents on the top.  Despite
employing no fan *and* using the same lamps as before, the
cooling is slightly better now -- that is, less heat gets
into the tank from the bulbs.

It's not always an option and not always a sufficient
method of moving heat away from an aquarium. But passive is
the way to go if you can.

Good luck, good fun,
Scott H.
