When I bought my used 30g it came with 2 heaters.
They're not submersible, so I would only use them in case of a heater malfunction emergency.
Can anyone tell me the wattage with the little information I can provide?
Also, if you have one of these, your opinions on them.
1) It's a Fritz PCB heater. The top is black. The dial has Low Medium and High settings (with little lines in between)
Under the top is says 110-120V 50-60Hz
It's made of glass and inside it says MP 103G 600V.
It has the attachment to hook on the side, so I'm sure it's not submersible.
It doesn't have a water level line.
2) This is a Penn-Plax. The top is brown with a red dial, it just has lines where you adjust the temp. On the top is says Therma flow PC.
Under the top is says 110-120V 50-60Hz
It's made of glass.
It has a high water line and attaches on the side, indicating it's not submersible.
On the cord it says 105 degrees (not the word, the symbol, but I couldn't find that on my keyboard) C.
It also has bunch of letters and number which seems to have no meaning.

Can anyone solve this mystery?
I'm going to be cycling my daughter's 10g using one of these heaters, so I'll be able to figure out where the dials need to be for the correct temp. (getting my sharpie ready. lol)
Thanks!
