Buy Aquarium Heaters

Review by MacGuffin:

I also use Marineland Stealths, which I like because they’re plastic but frankly, it bears mentioning that Marineland’s “lifetime guarantee” carries an Orwellian caveat, i.e., some Stealths are more guaranteed than others. Rather than providing mail-in product registration to activate the warranty, you’re expected to hang on to your receipt…well…for a lifetime (yeah, right). In addition, if they don’t like the vendor, e.g., you bought it brand new and sealed but from an eBay or Amazon seller, you can kiss your hopes of replacement for a defective unit goodbye (they claim this is due to widespread fraud and people trying to obtain replacements for units found in the trash, but why were so many units trashed if they work forever, and who are these dementos who make a career of scavenging for them? Liver-lipped Finnish Ugly Boy trolls?). Marineland (actually, Aquarium Systems; they manufacture the item in Italy), after much coaxing, replaced a brand-new dead unit for me, but it’s only carrying a 90-day warranty; this is because I bought it on eBay and I received an e-slap to the effect that NONE of my other Internet purchases would be covered. On this basis, my suggestion is to boycott Stealths (unless you want to pay list at a pet store) and go with a Theo. They’re also manufactured in Italy, they do a great job, and I suspect they’re nicer about warranty issues.

Review by C. Huskey:

Also, it’s worth mentioning that the heater doesn’t look exactly like the one in the main picture. It’s shorter and fatter (proportionately at least…) than pictured. This isn’t a bad thing. Just don’t freak out, because you ARE getting what you ordered.

Hydor MINI HEATER Aquarium Heater 7.5 Watts for Tanks 2-5 gal Reviews

Review by Brian J. Williams: This heater works well, not bad for small tanks (5 gallons or less). I purchased this for my 1 gallon tank, and it heated the water up to the low 80s. The heater works submerged or placed under the tank. I keep my apartment on the cool side, so this heater did the trick. A word of warning, though–if you have a 1-gallon tank, make sure you have a thermometer in it, because if you keep your home temperature in the high 60s and into the 70s, chances are the heater will then heat the water too warmly, into the mid to upper 80s, at which point you’ll have to unplug the heater and monitor the temp as needed. Still, not bad for the price.

Review by M. Lee: I bought these for my 2.5gallon killifish tanks. These heaters take up very little space in the small tanks, since they are flat.

But be aware that these heaters don’t have temperature controls, so the water temperature will change when the room temperature changes. My tank temperature ranged from 92F to 70F with the heater plugged in from May to December. I had to unplug the heaters on very hot days. It seems that these heater will raise the water temperature in a 2.5gallon thank by 8 to10F over the room temperature.

Finally, all 6 mini heaters that I own have been reliable for 8 months now, and all are consistent in how much they heat the same volume of water.

Review by P. Liang: Placed it in the water horizontally (completely submersed), works perfect. Has a little red light that shows when it is running which is somewhat hard to see in this mounting position, but all in all a good heater, no fuss.

Review by iza425: This fishtank heater works great. I’m using it in a 29 gallon tank. I set it to 79 degrees and my temperature strip on the tank shows 78 degreees. I’d say it’s accurate. I recommend buying it.

Tetra Submersible 50-Watt Heater Reviews

Review by HP: I was researching on a good heater for a 1.5gal fish tank, and I came across the Tetra submersible HT 10. It fits very well into the tank, and the heater maintains a constant temperature at 76F. I am satisfied with this heater. However, you cannot change the temperature setting. It has been 3 months since i bought this heater, and i have no complaints yet. My fish is healthy and well heated with this HT10 from tetra.

Review by S. Pinkston: I have purchased 3 of these Tetra Heaters in the past 5 months, and all of them have quit. The warranty only allows you to pay shipping both ways, either to fix yours, or they will send another one. I do not want any more of these Tetra heaters, and am looking for another brand. I wouldn’t waist your money.

Hydor THEO Submersible Aquarium Heater 200W UL Reviews

Review by Turtle Lover: This heater works great I have it set just a little bit higher than it’s lowest setting and it is working great. I have it in about 50 gallons of water and it handles that with no problem…

Review by kenneth: This heater has exceeded my expectations. Although, I expected this heater to be a little be longer being that its a 200 watt compared other other brands it was very strong and kept my 80 gallon tank heater and it was percise.

On the box it says that the 200 watt heater is for tanks up to 56 gallons. I find that it is good enough for a 80 gallon.

Hagen Aquarium Radiant Heater 100 Watt 10 inch’ Reviews

Review by E. Steward: The heater is really good for my 39gal tank and actually I think it would be capable of heating a larger tank cause it can get my tank to 90 degrees no problem probably can go higher. I keep my tank at 80 though. The only bad thing is I have to fill my tank to the top to cover the water line of the heater and I like to leave my tank 2 inches of room. Also the glass is frail so be extra careful with it. Lastly the cord is short and I have to use extension cord to plug it in. Hope this info helps!

Review by Michelle Ewald: My son decided to start a fish tank – 29 gallon. We searched the net for heaters, this one had great reviews at Amazon had it at a great price. We’ve had it several months with no problems at all.

Hydor THEO Submersible Aquarium Heater 100W UL Reviews

Review by Tastinient: The unit consistently delivers the same temperature, which is good, but that temperature is always about five degrees higher that where I set it. So if I want my tank at 77 I need to set this to 72. These products are all about accuracy and consistency, and this unit has not been so great. I’m too lazy to make a warranty claim, but I figured other customers should know my experience.
