"Works great."

This does a great job at regulating the temp in my 10 gallon. Well I bought a second one took me only one trying to get the right temperature. The heater is being used in a 40 gallon breeder. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. I'm in the process of setting up for tanks. Well I bought a second one took me only one trying to get the right temperature. We would consider a replacement and then we would return the defective unit.

BOEESPAT Final Thoughts

"Yes, you read that right."

I use a 50 for a 5 gal and a 10 gal tank. It would stick out of my 30 g wide tank if I were to put it vertical. I use a 50 for a 5 gal and a 10 gal tank. It is a bonus that the heater is titanium. --Temperature adjustment labeling is on top rather than on the rod. But I am single and don't have to worry about this. Or better yet, conceal it to the back corner.
