Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
Just FYI, Was looking into a chiller for my 30 and bought one of these fans in the interim. Works so well (4F drop) that I’m not going to bother with the chiller.
I bought a chiller a couple of years ago, ran it for one season destroyed my electric bill. Now I use a fan like mentioned except it’s the three headed one.
