"5 gallon tank."

I went ahead and went with the the larger 300W for my 45 gallon. The heater is super thin and the reflective surface is interesting. The bonus digital thermometer it came with has been super helpful, and is accurate. We wish the controls were available in Farenheit also to make things a little easier. Bought it as a chiller for the k40 CO2 laser. Pressing and holding the button for 5 seconds changes it from F to C readouts. Beware, but we are hoping for a good outcome!

  • SunGrow Betta Plakat Heater, 10-Watt Submersible Aquarium Water Heater for Small Tanks (1.5-Gallons), with Preset Temperature Capability, Suction Cups Included
  • ✔ KEEP YOUR BETTA HEALTHY --- To ensure that your betta has optimal health, you need to provide her with warm water. The water in the tank should not go below 74°F for optimal comfort and metabolic efficiency of your crown tail betta. The cold temperature for this gourami family fish will make her lethargic, stressed, and miserable.
  • ✔ AUTOMATICALLY REACHES THE PRESET TEMPERATURE --- The smart SunGrow heater for this freshwater fish has a built-in electronic thermostat to automatically maintain water around 72°F which is ideal for most tropical fish. It saves you from the trouble of constantly keeping a check on the temperature of your tank. It will automatically shut down when it will reach the desired temperature, no manual adjustment is needed.
  • ✔ CREATES THE IDEAL CONDITIONS FOR FLORA AND FAUNA --- The eastern Asian fish species can survive in a freshwater environment. This heater by SunGrow will create ideal conditions for them. A few preconditions are required to allow it to run with maximum efficiency. The heater must be completely submerged in the water and the indoor temperature should be around 62-74°F.
  • ✔ SUCTION CUPS INCLUDED FOR EASY INSTALLATION ---- Easily install the SunGrow Heater vertically or horizontally by using the built-in suction cups to attach to your tank. The best location to place the heater is in the stream of a powerhead or near the water flow, such as the outlet (or inlet) from the filter. This way the heat is evenly distributed throughout your tank.
  • ✔ FULLY SUBMERSIBLE WATER HEATER--- This 10-watt aquarium heater supports 1.5 gallons (5 liters) fish tank. Its exterior is designed with tougher than glass and the sealed polymer can be submerged into your tank. The heating element is surrounded by a thick plastic to ensure the protection of these caudal-finned betta fish.

SunGrow Final Thoughts

"Temperature!"

It would stick out of my 30 g wide tank if I were to put it vertical. It took about an hour to reach 80f, which is fairly quick. My fish likes to get close to it and he has never been hurt by it. Was very impressed with the quality of this heater. I left seller feedback yesterday but have yet to hear from the seller. I will be ordering more of these in the future. We received the chiller promptly and put it into use.

"Best value."

The bonus digital thermometer it came with has been super helpful, and is accurate. Ick for instance detaches from fish at 86 degrees and dies at 89. Well worth the money the first one I bought still works great. This has been in my fish tank for a few months now and it's been absolutely perfect! This heater works, but the dial it isn't very accurate. I like the fact that it comes with a digital thermometer. The temperatures are pretty accurate.

"Works just as advertised!"

For Discus you need warm and accurate heater and this seems to do the trick. This heater works, but the dial it isn't very accurate. Also were nice along the whole process. There is no protection from it banging on the glass tank. Two inches above that is a waterline for maximum. I wouldn't buy any other heater, unless one of these stops working. Am a totally sold customer and would recommend them to anybody!

"No copper lines!"

I used to try those other cheap heaters sold on amazon. No biggie, but annoying nonetheless. It is a bonus that the heater is titanium. My heater is fully submerged underwater and works perfectly fine. The heater is easy; turn the dial to set temp and plug in. --The heater itself is a bit shorter if your tank is a short one. There is no protection from it banging on the glass tank.

"This is a quality heater."

Checked the accuracy of the heater with an infrared thermometer. Two inches above that is a waterline for maximum. I use this little heater for my 10 gallon quarantine tank. You program it for temperature you want your tank to be. This is a powerful heater that holds temperature very well. It just cycles through to 93f and starts over. I will definitely be buying another one for my other tanks at bigger one.

I will definitely be buying another one for my other tanks at bigger one. Just be careful and keep an eye on your temp settings when you have kids over! This heater is NOT fully submersible. The controller is easy to use, very accurate and reliable. I wouldn't buy any other heater, unless one of these stops working. The suction cups are large, high quality and seem to stick great. The temperature gauge is fairly accurate in my 55 gallon tank.

"9 degrees."

The temperatures are pretty accurate. Awesome chiller, perfect for Hydroponics. The heater is being used in a 40 gallon breeder. What more could you ask for great job Hygger Duncan. They shipped us the upgraded version that also heats! Come on Fluval, expect better from you. I like to keep it at 72 and from my thermometer it is reading at exactly 72.

Once attached to the tank wall I've had no issues with it coming off. And I get to keep the first one I bought! They promptly fixed the issue without any delays or drama. Those turned out to be a hit and miss. My marina heater takes a few hours. I was worried about the quality but I am thoroughly impressed with this heater! I'm not a big fan of the big glass tubes.

"Great concept."

Keeps the temperature within 1 degree of what you set it to at all times. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. The temperature has been holding all day, even in a colder room. I think it works well to not stand out like other heaters. It is a bonus that the heater is titanium. Once I opened the box i noticed the quality of the construction. I have it set to 81F to get a 77F water temp.

  • Lineba 500 Watt Submersible Aquarium Heater, Fish Aquarium Heater with LED Temperature Display for Fish Tank
  • *Very easy and reliable to use. After well installing the aquarium heater and the thermometer, you just need to set the desired heating temp, then it can ensure the temperature constant at the set point with the blue indicator light,as it can adjust heating power automatically if there is any water temperature variation.

"No issues."

It took me a few days slowly turning the dial up to finally get it where I wanted. The bonus digital thermometer it came with has been super helpful, and is accurate. The line is there due to regulations in certain countries. I have it set to 81F to get a 77F water temp. The cover over the heating tubes is great, the turtles claws can't damage the tube. The temperatures are pretty accurate. I dont know, and havent tried just yet.
