Review 1 for Tetra Submersible Aquarium Heater, 50-Watts
Heater Must Be Used Correctly
,12/02/2012

If water does not circulate in the area around the heater, the heater's internal thermostat will quickly reach it's design point for cutting off power to the heater and it (properly) quits heating. Also, the volume of water and the room's ambient temperature will affect the ability of the heater to do it's job of maintaining a stable temperature in the aquarium. The more the room temperature is below the heater's setpoint, the harder the heater will try and will possibly fail to maintain a stable temperature. My heater is used correctly and it has served me well.

I bought this heater for my daughters new betta fish 2 gallon tank. I love the fact that it suctioned on the side of the tank & also has an auto shut off when it reaches correct temp. He dif. seems to like it being warm.

was hoping it would do the job for my 10 gal tank but it wouldn't keep the temp above 70 even when I added hot water to raise it to 78 it would drop back to 70
worthless
I took it back to the store and got the same one only 100 watts and it work just as bad and failed is the same way

Review 6 for Tetra Submersible Aquarium Heater, 50-Watts
Use for Turtles, very excellent
,07/19/2012
By fangs211 ,

Turtles will not eat if it's cold but they will not go into hibernation if it's not cold enough. My two turtles stopped eating around winter. They became skinnier and retreated to their hide-y cave. It worried me a bit because they used to be excited eaters, rushing to the side of their tanks and waving at me so I could come over and feed them. And no matter how much I fed them, they wanted more food. So I did some research and I found that piece of information in my first sentence.
So I went to the store and bought this, washed it and plugged it in. Just a few hours later, they returned to their old begging-dog self. It works great, keeping the temp at a constant 65-75 degrees that the turtles need.
Only thing is that my turtles don't like a lot of water for some reason so the heater is half in the water, half out, even if I stick it at the bottom of the tank. But no worries. The turtles lay on it to keep even warmer. It doesn't burn their shells...

I got this heater yesterday and my tank is now at perfect temperature. Before I got it my fish (guppies and mollies) where not really swimming around and now they are.
Love it and would recommend it for the price.
Hopefully it works out ;o

Mine died too.

I have a 30 gallon long aquarium and managed to break my 300 watt non-submersible heater that was 8 years old (I think it was a Tetra too) by letting the water level get too low. It was still working fine prior to the incident. I purchased this 50 to go along with another submersible 50 watt (adjustable) that I had thinking that 100 total would be fine, and it was. The heater cycled on and off and maintained temp normally. After a couple weeks I noticed that the water was getting too cool and the red LED was off so I unplugged and plugged it back in and it came on. Now it will not come on at all even with the water temp at 64° so I took it apart to see how it worked. It is based on an LM324 quad op-amp and 2 temp sensors that appear to be thermal diodes but are labeled NTC on the board. These 2 sensors drive 2 of the 4 op-amps and the output of the 2 drive the third which controls the triac that switches the power to the element. The fourth op-amp is unused. The red indicator LED and its dropping resistors are hooked directly across the element. I think moisture may have gotten in and ruined the electronics. It is not serviceable as it is glued together with CA (super glue) and I broke the glass tube trying to take it apart.

72 degrees is NOT a tropical temperature

I bought this heater a week ago and since then my 5-gallon aquarium has not reached more than 72 degrees. Tropical fish ideally should be kept in water between 76 and 82 degrees and this heater doesn't even come close. I guess you get what you pay for, but I will definitely be returning this product and spending the money on a good quality heater.

Not reliable in the long run

I bought this heater about a month ago. For about three weeks this heater was doing exactly as it is suppose to do. However, it randomly started losing it's heating power. Instead of heating it to 76 degrees, it is now at 71 degrees. A 5 degree difference really affects a fish's health. Do not buy this heater because you'll have to buy another heater in the near future.

Betta Fish no longer shivering

By JTavarez

I was not aware that a Betta fish prefers a warm environment. When he stopped moving or eating I researched the symptoms on the net. Sure enough, they like it 78 -82 degrees. Without a heater it was about 68 degrees. Burrrr. The Tetra heater is the perfect size and has made all the difference in his quality of life. So far it is a steady 78 degrees and he loves it. The heater is under the rocks out of sight. It was so simple to find it, pay for it on Walmart.com and have it shipped to a nearby store. :-)'s

USELESS - STAY AWAY PLEASE!

I purchased this heater less than 2 months ago and it already STOPPED working. It definitely doesn't keep the water at the 78-80 temperature. Currently it only goes on when I unplug it and plug it back in, but afterward it will not turn on again until I unplug and plug it back in. It is a TERRIBLE TERRIBLE product. It says it has a 2 year warranty, but you need to have kept the receipt and pay them $3 extra for shipping. Which means you pay money to ship it back to them, and then you provide money for them to ship it back after they "fix" it. They won't provide you with a new one, but only PARTS. PLEASE DO NOT PURCHASE THIS TERRIBLE PRODUCT.

The warranty you mentioned..
Posted 10/09/2012
Just clarifying your info about the warranty. I've actually exercised it after one of these heaters malfunctioned (wrote them a nice little note too). The element burnt up in it and I woke up one day to find my tank at 91 degrees!! The heater thermostat stopped working so it never shut off. I did do the warranty, even though it cost me about 6 bucks total ($3 for them as you said, plus my cost to ship it). But it was still cheaper than another $20 to replace it. HOWEVER, they DO ship you a complete new one, in packaging and all. Not just parts as you said... you're wrong there.

What a piece of junk. Water is at 65, set heater to max setting. Heater goes on and internal stat say oh my, its to hot so it turns it back off again. Cycle starts over again. Never stays on to heat up the water. I blame my self for thinking that such a simple thing would just work and not doing the research.

I have a 10 gal tank. I just lost all the fish because this heater isn't really up to the job. The A/C is on in the house and the heater couldn't keep up. Buy a heater designed for a 10 or bigger tank.

I purchased this heater about 9 months ago as part of a 5 gallon aquarium kit. It worked great for the first 8 months but has sinced stopped working. The tank temp now is around 70 degrees and I noticed that the heater never seems to turn on. As there are not many choices for heaters for a 5 gallon tank I'm not sure what to do.

I would really not spending money on this. It says it keeps it up 78 F, in reality it doesn't. This is suppose to be for 2-15 gallons. I use it for a 1.5 and still cant get past 72 during day and 70 at night. Don't waste your money on this.

Maybe your thermometer is wrong? Mines stays around 77-78 all the time... I've had two now and they both have always kept the temp where it's supposed to be. OH, and I put this one (meant for a 10 gallon) in a 29 gallon tank... 77-78 all the time. Can't beat that.
