Right now I am using my 2nd Hydor Theo Submersible heater (50W) for my 10g. Our house is pretty chilly, so I recently purchased this heater. This is actually my 2nd heater, as the first one didn't seem to keep the right temp. My thermometers would say 77, when I had the heater set at 73.
I am experiencing the same situation with this 2nd heater. I see it keeps kicking on, when I have the temp set on the heater at 73; the thermometer is reading 77. I'm just trying to get the temp down a bit.
So my first question is:
Do submersible heaters always kick on and off regardless of what you're trying to get the temp at? (It doesn't seem right). To get the temp to go down is the only solution to unplug the heater?
Second question is:
What heaters do you recommend? I read titanium heaters are pretty good. Does anyone have any suggestions on a brand?
Appreciate your input!
