Trouble with Hydor 25 Watt heater.

I bought this heater a little more than a month ago to heat up my 2.5 gallon, but now it's been moved to my 6.6 bookshelf tank that houses my Betta and four Ghost Shrimp.

It's set at 79 degrees, but I found out when I got home this evening that the water temperature was 84 degrees and the light was still on.

So, I lower the temp to shut it off. I then turn it back up to 79 and right now the light is back on and my tank's temp is at 82.2

The thermometer and heater are at opposite ends of the tank.

Has anyone used this heater and have trouble with it? I don't want to leave it on all night, but I'm afraid with the weather getting colder at night, I'll wake up to a dead fish in the AM.

Is it a Theo? I had one do that, but only after I'd used it for about 5 years.

i have 4 theos and found them to be the most reliable. i just threw away two Elite 25 w heaters, one of which overheated and killed two of my bettas.

I'm starting to wonder about Hydor's reliability lately.

I bought an inline heater that didn't work at all, straight out of the box.

I bought it 3 months ago for a new tank I finally set up last week. The place I purchased it from only has a 60 day return policy so I had to contact Hydor.

It has a 2 year factory warranty but Hydor won't reimburse shipping so it cost me another $16.00 to ship it to Cali.

The said they will repair or replace it and ship it back to me.
