It says it's supposed to shut off when it reaches the best temperature. There's no way to adjust it. I'm going to exchange it for a 25W one that I trust. Thanks for the help!Um.. I'm assuming it's adjustable? If not you might want to reconsider >.> I've got a 25w that's adjustable and it works perfectly... I'm not quite sure what a 50w would be like in a 2.5...
Thank you!Ah... The heater I have is the only heater I've ever dealt with. I haven't heard any great stories with non-adjustable heaters, but they're not allllll bad. It seems like 50w would definitely be a high risk factor with a 2.5g, though.. I know I set my heater for 80 degrees exactly and after a day had passed, the temperature on both thermometers I had in the tank at the time were reading 4 degrees over their original temp (they're like two degrees apart). The heater was over $20, but from all the reviews I've read and the people that have given me recomendations off of this site, it's definitely the best heater I've ever gotten- with hardly any doubt that its going to fail me in the long run. I originally wanted to get a cheaper one because I thought it was going to be more cost efficient, buuuuuut it seemed like I was gonna have to spend even more than I wanted to because of how short a lifespan the cheaper heaters had >.>;
But yeah, I hope the heater search goes well for you ^.^ Definitely try to read and get as much advice as you can about them! It's kind of time consuming, but it definitely seems to help a ton!!
Yes it is the Tetra preset heater. You said you use a 100W in a 2.5 gallon tank? So the 50W preset shouldn't be too much then? I might try it to see it it works correctly. If not I'll look into the elite mini heaters. Thank you!Is it the preset tetra heater? If so it will probably not overheat...I have 2 of the 100 watt preset tetras..one in a 2.5 gallon and one in my 10 gallon QT. tank...the 10 stays at 76 degrees... the 2.5 stays around 80.
Adjustable heaters are best because you can adjust them according to your room temperature...For example..In winter when it is slightly cooler in our house I may need to adjust my aquarium heaters up slightly if iwant them to remain around 80 degrees...With the preset heaters you cant adjust them up so your fish are kinda just stuck with the temperature swing..Most presets only raise the temperure up a few degrees depending on room temperatures.
I have heard good thing about the adjustable elite mini heaters. I personally use the penn plex adjustables from pet supermarket in my smaller tanks..Theyre about 14 dollars.
