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.

This heater doesn't heat the water to its set temperature. I had the heater in a gallon bowl for my Betta fish. This heater is for tanks up to 2.65 gallons so the size of the heater was right for my tank. I measured my temperature with a glass thermometer that sits in the tank (these thermometers are more accurate than the tape on thermometers). The temperature of the tank only reached 63 degrees, too cold for a Betta.

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.

Based on other reviews, I was leery of purchasing this heater. However, I liked its sleek design for my 1 gallon betta tank and took a chance. The tank is sitting on a granite counter near a window and the house thermostat is set at 67 degrees. So far, the heater is working perfectly, keeping the water a constant 77 degrees.

Purchased this heater on sale at Petsmart. It worked for 2 weeks and stopped resulting in freezing water for the guppies. We lost one and are on the verge of losing another. Don't waste your money on 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.
