Didn't really read the specs on heater before it arrived, so was pleasantly surprised to find it a submersible heater! Works great, hasn't come unattached from the aquarium like my last one did. Is perfect for angelfish, keeps the tank at a steady 79-80º! For the price, can't beat it cuz I looked online a lot til thought, why not Walmart?? Thanks again Walmart.

I bought two of these heaters (200w) for one tank (20 gal, one for a backup). At first this product worked great. Red light, heating and green light, at temperature (standby). Both were working then one stayed on green and has not worked since. I tested in a bucket of water and it never lights red or heats the water. So now I have only one heater, questionable if this one will work for long. It has been about six months now and I will have to return this for a warranty exchange (pain in the product). I should spring for a quality heater with these slim lines and function. No knobs, all internal and automatic are all great features. That it does not last is a terrible knock to Tetra's trade-name and goodwill.

I have bought two HT30's within the last few years. It's a nice and simple product. You completely submerge it in the tank and never have to set it because it's fixed at 78 F. Unfortunately both failed within two years of buying them. The first one began heating the tank up to the mid-80's. This happened within the warrant period but I hadn't saved the receipt so I just called it a fluke and bought another one. The second one I've had about 18 months now and just this week I noticed it was heating the tank to just under 70. I have the receipt this time, so I'm going to try to exercise the warranty. It's a nice little heater but apparently not very reliable.

I have 2 five gallon tanks in operation for about two weeks. Installed a HT10 (50 WATT) heater in each tank.to keep my bettas comfortable. Temperature holds at 78 which is just what I want. Happy with these heaters so far.

  • A. The package states it works for 10g-30g.

  • A. I bought a 50 watt off Ebay and it never heated the water in my 10 gallon tank. The 100 watt is what you need. Its time to replace my heater because it heats the water then shuts off but does not come on again to maintain the proper temp.

  • A. No, buy the 50 Watt. It is more suited to your smaller tank.

  • A. yes, I am using these in several 10g aquariums. I haven't had a chance to see if there is more power consumption over the 50w version, but it keeps the temp right where it says it will.

  • A. You shouldn't get a heater that's more powerful than you need. If something were to happen to the heater's thermostat, a high-powered heater would overheat the tank. Many people prefer to use two small heaters so if one won't turn off it can't overheat the tank, and if one breaks completely the other will still provide some heat to the tank.
