cooling canopy question

[mike12345]

my question is there any speical kind of fan or what speed would one recommend to keep two 175 watt metal halides cool underneath a canopy thanks in advance and where can you get these fan from

I have been using the Coralvue smart fans and they surprisingly quiet and would speed up based on how warm yoru canopy got.


Much quieter than the ICECAP smart fans.

Try Tony at www.acropora.net

don't need to, they mount to yoru cannnopy just like exhaust fans.
