This heater kept my 2.5 gallon tank in the low-mid 80's. Way too warm. I ended up replacing it with the Hydor 25W heater because it has a dial to set the temperature. It's much more reliable. Though this one is 3.75" and the Hydor is 6.5" long.

110.. Mine worked for 6 years and then died BUT IT DIDN"T overheat.. It just wouldn't keep the aquarium warm anymore.. None of my fish died and if you are checking it daily it shouldn't be an issue.. I believe these are great heaters! I now have another that is 1 and a half years old

Hi -- I have a 2 gallon tank and it is working good. I recommend buying a cheap additional water thermometer and then setting the temperature on the heater to be slightly lower than the desired. For example I set my heater to 74 to get an actual temperature of 80F (as measured by the second thermometer).

I've had a Betta Tank for 2 years and this thermometer has worked great so far. Between 50 and 90 degrees. I keep my Betta at 76 to 80 and it stays within 1 degree all the time. You would need some moister to keep the thermometer sticked to the tank however. A great tool anyway.

I have a half filled turtle tank. I bought this a few days ago. My digital thermostat is at opposite end of the tank. Yesterday I noticed it rose to 82 degrees. The water was pretty warm to my hand. This may have something to do with the heat lamps being on as well. I now monitor the thermostat regularly and turn the water heater off periodically.

Well it overheated my 5.5 gallon and killed my fish so it would probably do the same to a 3 gallon. Please do not buy...

I had this heater in a 3 gal 360 tank and it kept it too warm. I ended up buying a heater that I could set the temperature.

I had the same problem and wound up buying a second one thinking it wasn't powerful enough to heat my 75 gallon tank. Even with two operating ( one on each end of the tank ) couldn't get the water heated above 74. Apparently these need quite a bit of water flow directly on them for them work properly. I wound up returning both as I wasn't rearranging my filtration to get a heater to work. Wound up going back to the old Eheim Jagers that work great.

I'm not sure, I have a 250 watt for 90 gallons which I am using in an outside pond - totally under water. And it's doing great. You really need to call a pet shop for the answer - sorry. Even if the wattage is overkill, it's oK ; it will not come on pass the setting you set. So if you set it on 76 degrees and the water in your tank is 78 degrees it just won't come on.

I use it for a five gallon tank and it is great. A one gallon tank might be to small. Prior to getting this I had a flat heater that was under my gravel that auto censored to keep a tank at the right temp. The only problem with it was I needed to have more control of the temp in the. You might try finding it, sorry but I don't remember what kind it was, but I know it was for smaller tanks.

The Aqueon is been unreliable for temp, I bought a Eheim heater and its holding temp well, for a tank your size the 300w should do the trick, rated for up to 250g

Many factors would determine which bulb would work best for you including the air temperature surrounding your tank. The water should be somewhere around 77-80 degree's and the light you put in for basking should make that area 10 degree's warmer than the water to encourage the turtle to bask. I would purchase the 75 watt and move it up or down to get the proper temperature. Better to have move than you need rather than not enough heat.

No. I have 2 5.5 gallon tanks and it does not overheat. It turns off automatically.

It heats the water to the desired temp. So it turns on "red light" when the degrees of the water is lower than the desired temp. If you set to 85F it will stay on until the temp of the water is 85F. However, I noticed it heats great but doesn't decide "temps" great. So I bought a Finnex Max-300 Digital Aquarium Heater Controller and the in-line heater will only turn on when my "much improved" controller tells it too. I have my controller set to 82F and my in-line set to 85F. So if the water is 81, my controller turns on power to the in-line, the water starts heating, and once the controller gets to 82F, it shuts off power to the in-line. I did this for "fault protection". I heard this in-line malfunctioned a couple of times, got stuck to 90F and never turned off. Fried all the fish in the water... Go get the Finnex Max-300 Digital Aquarium Heater Controller, you'll thank me later!

I have a male guppy, neon tetras and two corys all in the same tank. I haven't noticed any problems. I think it's safe.

This easily/consistently keeps my 10G tank at 78-80F. Should easily suffice for a 1G tank. You could go w/ less wattage but I don't recall saving much $ over a smaller one.

I used it in a 20 gal tank for angel fish fry and it worked out just fine. Just make sure your air pump is rated for the 29 gallon and not too high. I had one that was for a sixty gallon and the air flow was too strong.
