Tank heaters revisited

[Pan]

Heaters have to be the most brought up and controversial aspect of have an aquarium, seems the most money potentially lost on one of the cheapest things. I'm still looking for "fireplugs" of the kind on oregonreef.com (I had one sent but it was damaged in shipping, got a refund but no more were available) That combined with an aquadyne controller....or maybe a simple ranco...or maybe a "KevCo" controller
