Thanks for the head's up. It was an extra I had laying in the garage, and I'm not that happy with how it looks in there anyway. Any other suggestions? Maybe a Jager one?
I like my Jager one but it's on the big size for wattage. I also like my Aqua Clear which is smaller, not much shorter. I am no expert on heaters, especially some of the newer titanium ones that look interesting, or external temperature controllers which I plan to buy soon. I would look at the hydor inline heaters as they get good reviews but the wattage is high for a 7.5 gallon so you should probably consider an external controller on a small tank, though many use these on sub 10 gallon tanks with no issue.
