The reviews on Amazon are very mixed, so I was wondering if anyone here has tried it and can tell me if it's good or not? Or if anyone can suggest another heater for 2-3 gallon tanks at a similar price?
At best you will want one that is totally submersible. I used to have an elite years ago that snapped on to my tank. It worked for the few years I kept the tank. But again, submersible ones are just as cheap and adjustable :)
I have an Aqueon submersible heater that's adjustable and has an automatic shut-off~ I paid $10 for it on Craiglist, and I'm unsure about it's price in the store (about $22 depending on the website.) However, even though the heater was used when I bought it, it works like a charm and Bo is warm and happy!
I'm unsure about the heater you were asking about, but if that doesn't work out, I would definitely advise an Aqueon submersible heater.
I'm sorry if this was less than helpful, but I wish you the best of luck! ^^
They have a Hagen elite model that is fully submeriable. I have 3 of them. If you have a tank under 5G, I recommend it because it is only 6 inches tall and will fit into bowls and Kritter Keepers. Most other heaters are too tall to fit. I have a 25 watt marineland stealth heater in a 3ish gallon and it barely fits.
Not sure why it says preset, it is adjustable
In the same boat as you Irishdancer, I have a Tetra 50W submersible heater for my 2 gal and it has been keeping my tank at about 76, rather than the 78 its supposed to, when I came home today and the temp was at 72!! My poor Weebles was really lethargic just sitting on the bottom. I had to stir the water around with a spoon to get the heater to come on. I'm really confused on which brand to buy now and hope you get some good advice on which brand to get. I'm not sure about you but I'm looking for one around $20 since my husband is still a little sore that my around $20 fish buy has now turned into more like $100 fish buy lol I have tried ebay, amazon, petsmart and walmart and all the bad reviews on all the heaters have me really scared to pick one.
Irishdancer, I have the 25W version one you posted from petsmart. I have used it in a 3 gallon 360 degree round tank and now in a 4 gallon square tank. I want to say it's around 8 to 9 inches tall from bottom to top of adjustment knob. so that should give you an idea if it will fit your tank.
As for performance I have nothing bad to say about it.
I have the 50W version of the first one in my 5 gal (because it was brand new and free lol) and while it does keep my tank temperature at a constant 81*, I have found that it tends to run a bit cold, so I have to turn it up higher than I would have thought. I tested it for about a month before I added any critters to the tank (intentionally... the snail infestation was unintended) and I have no problems with it. Although, as people say, you'll want to watch your water levels so that they stay at the thermometer's min water line.
