Small Heaters

[Celura]

I only have a small 2g tank right now, but do they make heaters for tanks this small? It gets pretty chilly in my home at times, and I also am looking at adding an African Dwarf Frog to my Betta tank and was told I'd need a heater.

Any help you can provide would be wonderful. Thank you! :)

I have seen 6 inch heaters, I cant remember exactly were though! try Dr's Foster and Smith web site as well as Big Al's, I think my local Wal mart may have had them as well.

Whatever you decide on, I would not recommend this model:

I've bought two and returned both of them. The first almost boiled my tank, the second did not work at all. Shell out the extra $$$ and get something with a thermostat you can set.

Edit: Fixed a typo. BTW, Visi-Therm makes a 25 watt model, and so does Whisper, but I would not recommend the Whisper as mine is not calibrated well.

I use 25-watt Hagen Thermal Compact heaters in my 2.5-gallon and 5.5-gallon tanks. Steady as a rock. My only complaints are that the knob is hard to turn because it's completely encased in the rubber stopper thing, and I seem to get condensation in all of them after a few months' use. Makes me nervous. I've now re-positioned them so that the rubber stopper thingies are no longer submerged in the water. This allows for no more moisture to seep IN, and also makes the knob easier to turn if it needs re-adjusting (which it never does once it's set to the temperature you want).

I agree that the "Junior Heater" is an awful product. It shot the temperature in my Eclipse System three to like 94F, once. I don't know how the two fish in there survived that, but they sure didn't look too happy about it. I do wonder how it might work if placed in a filter box, though.

I've had two of the Visitherm Deluxe 25 watt heaters which are supposed to keep a constant temperature of +/- 1 degree F when dialed in but neither was reliable. The one in the 5 gallon tank never would shut off at the temperature it was set at (75 degrees) and would often zoom up to 81-82 degrees. The one in the 7 gallon tank was a little more reliable at first but after a month it started exhibiting the same lack of shut-off problem. I bought one from a LFS and one over the internet so I don't think it was just a bad batch. Also, the red temperature control knob on the top was extremely hard to turn, my wife couldn't do it. :shake:


I now use Hagen Tronic 50 watt heaters and can't say enough good things about them. They are 7 inches long.
