Calling Reeflow Hammerhead owners

[SDguy]

I was having some heat issues with my hammerhead on a CL. You can see the thread here . I think things are getting better, but I would like some input from other hammerhead users. How much heat, if any, did yours impart onto your tank? I'm especially interested in CL experiences. Just want to know what to shoot for, reasonably.

Thanks all in advance.
