Marina C10 Submersible Aquarium Heater (10 w)

The thermostat is set to 68F rather than the advertised 76F. If 68 degrees is what you need then buy it but if you, just like me, need a constant 76-78 degrees then don't waste your time and money on this good looking heater because looks is all it has.

I just bought this stupid thing from Petsmart. I followed all of the instructions and the thing won't even turn on! It says that you put it in the water, plug it in, the light comes on and you're good to go. BUT NO! The light never came on and it's not putting out any heat. My poor betta is going to freeze for another week until I can get a different heater delivered. It's really hard to find a heater for a small tank less than 2 gallons. This one is supposed to be for tanks UP TO 2.65 gallons. I have a 1 gallon tank. *Sigh*

Buy Marina C10 Submersible Aquarium Heater (10 w) Now

I just got this heater today from Petsmart since it was on sale and I was looking for a new heater. I had the Hydor Mini going, but because it only heats a few degrees above room temperature, it just wasn't good enough --we live in a house that gets very cold, and we have a space heater in the room that we only put on when we're home (thus, our room temperature would fluctuate a lot). Given, the Marina heater has been in for only a day, but my fish isn't huddled by the heater anymore and he is a lot more active. The water seems to be staying consistently at the correct temperature and I have a 2 gallon tank.

Edit: So I had it for a couple of months before it began to die. Then my poor betta would just sit next to it waiting for it to come on. I don't think I'd recommend this if you want a lasting heater.

Read Best Reviews of Marina C10 Submersible Aquarium Heater (10 w) Here

I was suprised to read alot of the negative comments about the heater because I'm a very satisfied customer. I bought the 10 watt heater for my tropical fish tank. It's been a couple of months now, and still works like a charm. What I love most about it is that it has a unbreakable casing around it, unlike most heaters out there and a very affordable price. I really don't mind not being able to adjust the temp since with this model it's at a constant 78 deg. I'm upgrading from a 1.5 gal to a 10 gallon soon, and I'm buying two 25 watt Marina heaters, instead of another branded 50-watt out there, because I know its reliable. The 10 watt even helped my fish through an episode of Ich, so no complaints here at all.

Want Marina C10 Submersible Aquarium Heater (10 w) Discount?

After purchasing this heater at Petsmart for my 1 gallon betta tank, I read the Amazon reviews and became disheartened, but tried it anyways. My room gets pretty cold, and the tank sits on top of the fridge next to the window where it is drafty (where else can you put it in a 3 person dorm room!?!?), so the temperature fluctuates between 76 and 77. It works perfectly, hides behind my black filter, and is made of sturdy materials. A happy betta lives here!
