I just got my titanium heater. I am very impressed with it.
Not only is it pretty much indestructable, but it has some other cool features too. The thermostat is on a seperate wire, not connected to the heater. This allowed me to put the thermostat in the aquarium, and the heater in the
sump. Now the heater comes on and off based on the aquarium temperature, not the
sump temperature. Also, the control dial is located on the plug, so you dont have to get wet to adjust the temperature, and the dial wont get stuck from calcium deposits building up on it. I highly recommend this heater. The last good thing about the heater is it only costs about $5 more then the glass heaters.
