Hydor 50W Submersible Aquarium Heater - Original Theo

Just bought the 50W model for my 10G tank. I set it to 79 degrees, and the thermometer agrees to this *exactly*, even on the weak side of the tank away from the filter.

I know that I haven't had it long, but so far, so good.

UPDATE: 2 months in, it still heats well. The ambient temperature in the room has an effect on it, but the temp is staying +/2 degrees from 80. For a $20 heater, I'm satisfied with that.

I ordered this heater because the one I already had was a little too bulky for my 5gal tank. It has been running for several weeks now and the only problem I've had is it runs about 3 degrees F above the setting but it is very consistent with the temp. I like how small this heater is without sacrificing wattage, I like the dial on top that has actual degree settings, I also like that there is an on/off light. I would recommend this heater.

It is a good heater. I think the temp might be a little off. i have it at the highest setting and the thermometer says 77 degrees, but it is in a very cool room

You may have to tweek the temp a little but this works just fine. It's not that long so it does not hit the bottom of my tank and I use a peice of drift wood to hide it.

I've been using this along with an Apex controller and my temp is always between 77.5 and 78. No complaints but I've only been using it for a couple of months.
