Tetra's HT line of heaters are easy-to-use and work in aquariums ranging from 2 to 55 gallons. The heaters have electronic thermostats that automatically adjust heat output to keep water at a constant 78 degrees F. All HT heaters have indicator lights to let you know when the heater is on, heating the aquarium.

All Tetra HT heaters have red/green indicator lights to let you know when the heater is heating(red) or on standby(green). The low voltage thermostat maintains water at 78°F without any adjustment required. Be sure purchase the correct heater for your tank size. Buying a heater too small for your tank can cause under heating. It is critical to ensure your tank is equipped with a hood or glass canopy to contain the heat inside the aquarium. All Tetra HT Heaters will shut off if an electrical short is detected for your safety.

This product comes in the following sizes:
HT10 (50 watt) - 2-10 gal
HT30 (100 watt) - 10-30 gal
HT40 (150 watt) - 30-40 gal
HT55 (200 watt) - 40-55 gal
Rated 1 out of 5 by from Bought a 2nd heater I have one heater for my 10 gal tank. I could not get it past 74. Purchased a second of the exact heater and still 74. Crazy! I can’t get my temp where it needs to be even with 2 heaters

Rated 1 out of 5 by from Failed :-( Was good while it lasted... After about 3 years of sporadic use, it over heated the tank by 10°C!!! Hopefully my betta survived..

Rated 2 out of 5 by from Not heating I bought this heater a week ago, but I don’t feel like it’s doing it’s job. It says it’ll maintain the temperature at 78 however mine has not gone past 76. Should I be worried? Is my betta okay with that tempature? Any feedback would help

Rated 1 out of 5 by from Isn’t heating water up I have had this 100w turned on for two days in a 10 gallon tank with 8 gallons of water. My digital thermometer reads 66 degrees. The lights are turning on but it’s not going any higher than 66 degrees. I keep my house at 68 so with the larger heater and not being a lot of water something seems to be wrong with the heater.

Rated 4 out of 5 by from Awesome Customer Service I have had an aquarium for 5 years. And a little over 2 years ago, I got into the hobby of aquascaping (5 gallons and 65 gallons). The heater in my 65 gallon tank is over a decade old and it is working just fine. The 50 watt heater I purchased 2.5 years ago (HT10) was not working properly. I saw 1/4 of my 5 gallon tank's water evaporated in less than 1 week time. I quickly did temperature check and it was in the mid 90 degrees F. Thankfully none of my inhabitants died. I did a quick water change to cool down the water and cleaned the heater just so that there was no buildup around the temperature sensors. I put it back in the aquarium and monitored the temperature for the next 3 hours. It passed 85 degree mark and I unplugged it. I bought this through Amazon 2 years and 6 months ago so I had the receipt. I decided to still contact Tetra to let them know the issue and see if they can help me troubleshoot the problem. Just today, I got a mysterious box in the mail and it was HT10 from Tetra. I never thought they were going to honor the warranty as it was past the 2 year mark. I already bought another brand heater, but I will keep this as a back up heater. Thank you Tetra. Maybe the heater I had was from a bad batch. Hope this one will last a long time. When it comes to electrical and mechanical equipment, some will last long and some will fail quickly, but what the company does for their customer really sets a company apart from others. I trully think that Tetra cares alot for their customers. If I were to give honest rating just for the heater; it will be 2 stars. However because of their exceptional customer service (replacing an item that is past the warranty period), I gave them extra 2 more stars.
