I think you must be lucky! I didn´t have any luck with it, but I tried it in a 5 gallon....

It didn´t raise the temperature over 68F.

I am interested if any of you would try it in a 5g??

I actually bought one of these about a month ago for my 2.5 betta tank, as yes the light heats up the tank sufficiently, but at night it gets kind of chillyblame my hormones, and the AC, okSo far I haven't had any trouble with it, and BadBoy loves itseriously loves itas he wraps himself around the heater and sleeps with it at night:%)(what can I say he needs some serious help, but wouldn't you if you almost went down the toilet)

So far my tank sticks between 80-82 degrees and doesn't fluctuate hardly at all...heidi

We've used the same heater. It works well in a 2 gal but doesn't cut it in a 5.

From what I've seen the temp swings are small enough and slow enough to not cause ich.

I've found the temperature doesn't seem to hold steady... it varies between 76 and 80. All told, though, it seems to work pretty well in keeping the temperature within an acceptable range. Considering this tank is in the basement, it has to fight against 65 degrees all day long.

The new betta that followed me home seems to enjoy his tank. He's flaring like crazy and enjoys his silk plants. Despite the fact that he seems to have quite a bit of fin rot (I hate it when they keep perfectly lovely bettas in horrid water conditions), he seems to be healthy. Apparently he has no problems with the slight variations in temperature!

It's Wednesday morning around 9:00 am and approximately 49 hours after placing this small heater in my 2 gallon aquarium. The room temperature is currently at 65 degrees as we turn the heat down at night. The current reading for the tank is 75 degrees F., so it looks as this heater is going to do the job.

Daka they did have some other heaters and I believe they had one marked for aquariums of 5 to 15 gallon size and if I remember the cost was under $10.00, but don't quote me on that.

do they have any larger than that? like ones that i could use to heat a 20l paludarium, so it' would only have to heat round 5-10g of water

Apparently the heater decided that 76 wasn't good enough. I keep looking in on it at 78 to 80. The brand new betta who is making it his home has absolutely NO problems with that level, though. He's one of the most active bettas I've see so far.

Despite the fact that the heat has gone up a bit, it seems to be staying steady now. Ut's been 78-80 for over a day now.

~Meow. Thus spoke the cat.~

It's now 8:00 pm and approximately 12 hours after I first placed this small heater into my 2 gallon tank. The current temperature is 79 degrees F. and has been there for the last 2 hours.

This is an increase of 15 degrees and seems to be holding steady now. There is no light turned on and the room temperature is at 70 degrees F. As I won't be into my office tomorrow, I'll update when I return on Wednesday. With continued good luck the "Little Heater That Could" will still be going strong.

They are submersible heaters, however they do not have any way to set the temperature manually, so they must be preset to heat to a certain level & then shut off.

Also, I'm getting ready to set up a 5 gallon betta tank and I will be testing one of these on that tank also - again before I add any fish. I will be purchasing a new heater for it so I'll be able to see if this working one I have now is just luck or not.

sounds like a good buy to me, although i'm a little worried bout testing in on the 2.5s since they have my bettas in them, now is this a HOB or a submersible filter?

Well, I've seen them and heard them mentioned, but never heard any feedback on them. These lil heaters are apparently 7.5 watts of 2 to 5 gallon heating goodness. I happened to be in the fishy department of my local walmart today and was like, heck, let's see what this thing does. For $6.96, I figured it couldn't hurt to run a test.

I'm being bad and trying this out in a one gallon tank (a previous buy from Walmart, actually). I believe the brand is Aquascene... those sorta triangle-ish tanks. I've got a handful of river rocks in the bottom, a thermometer (filched from another tank for purposes of this test) and the heater in the tank. The lighted hood is currently on.

The one thing that truly concerns me about this heater is that there's no way to set the temperature. You plug it in and you're stuck with whatever it gives you. I thought this heater would do well for bettas, which is why I chose to use one of the old tanks I kept my bettas in. After testing this tank, I may well go and see what it does for my two gallon tanks.

At approximately 20 minutes to seven, I put in 78 degree water, which is approximately the temperature that my bettas live in. I'm in the basement, so it's a bit chilly down here compared to daily temps upstairs. However, I figured this might give a good indication of how the temperature would fare overnight for those of us whose house heat turns down during the night. The thermometer reads it as about 65 degrees in the basement (no wonder I'm freezing!).

It's currently twenty minutes after seven. The temperature has dropped a degree and seems to be holding steady at 77. I'm going to leave the light on for a while before turning it off and seeing how much the temp drops (if it does).

In the meantime, I'm seriously tempted to stick my poor chilled fingers in the tank...

Just returned to my office and the reading is:

4:00 pm - 76.5 degrees F.

I will continue to monitor and put an update in before I leave for the evening and as a I won't be in my office on Tuesday it will give this heater a couple of days of testing to see if it is going to be able to hold this temp. and hopefully keep working. So far so good and as Kitten stated at a cost of only $7.00 US not a bad investment.

Seems to be working pretty well on this end. I figure with lights off and the ambient temp at 65, the tank stayed about 75. With lights on, it's 76 or 77. Not bad for this lil heater.

I wish there was a light indicating when the heater was on. I'm thinking that most of the heat above the 75 is pretty much being held up by the light.

Despite the shortcomings (lack of light or temperature settings), it seems to be a nice lil heater for a nice little price.

The 'net died last night and I was too bloody lazy and tired to come back and report... temp stayed at about 75-76 all night. It currently reads 75 and it's 11 in the morning... so it's held the temperature basically steady for over twelve hours. Very nice.

For seven bucks, I don't know how long it will last, but thusfar, seems like a decent buy.

~Meow. Thus spoke the cat.~

You guys are getting lucky, i stuck one in two gallons of water and left it for over 24 hours, and it didn't go above 68.. coincidentally room temperature...

I'd be interested in seeing what you guys come up with. I'v have had a couple of them and had terrible luck. Didn't heat up at all, died after a short time etc.

It's 8:00 am on Monday and I just got to my office. The temperature of the 2 gallon betta tank (no fish yet) is at 64 degrees F. and I just placed the heater into the tank.

I will be monitoring the temperature at 1/2 hour intervals and will edit this post with the data for any that are interested.

8:00 am - 64 degrees F. 8:30 am - 66 degrees F.
9:00 am - 67 degrees F. 9:30 am - 68 degrees F.
10:00 am - 69 degrees F. 10:30 am - 70 degrees F.
11:00 am - 70.5 degrees F.

As it appears that this little heater is raising the temp. by approximately 1 degree F. per 1/2 hour will begin to monitor and post results on an hourly basis.

12:00 pm - 72 degrees F. 1:00 pm - 73.5 degrees F.
2:00 pm - 74.5 degrees F.

Well this little heater has in the past 6 hours raised the temp. in this 2 gallon tank from 64 degrees F. to 74.5 degrees F. a gain of +-10.5 degrees. Not too bad for this small heater. As I have to leave the office for a couple of hours I will resume this post when I return.

The light's been off for an hour and the temperature is about the same. Looking good!

Edit: Two hours now... still good.

*grins* Well, then you're quite welcome to post your findings here when you test yours out.

I just turned off the light, after having it on for an hour. I want to see how well the heater is going to adjust to the light being off and having to fight the 65 degree ambient temperature by itself. Those tiny little incandescent nightlight bulbs put off a fair amount of heat!:88)

Final temperature with lights on was hovering just a smidge under 77 degrees.

Kitten, I just bought one of these same heaters on Friday and planned to test it out in a 2 gallon tank I'm setting up for a betta at my office.

I still haven't placed it in the tank yet, but plan to sometime this week so it will be interesting to exchange info to see if they work relatively close to each other.
