About SunGrow Water Heater, 10W, Turtle Aquarum Tank
65% liked the built-in monitoring system accurate, but 35% found it unreliable.
The heater maintains a constant temperature of 79 degrees Fahrenheit, which is ideal for small tropical fish and bettas.
My tank's temperature fluctuates wildly and is not accurate. The ambient room temperature is always around 68 degrees, yet the tank temperature is all over the place. One day it can be at 79 and the next day it will be 73 when theres been absolutely no change in the room temperature!
All three heaters have different readings and there is no air current that would affect their performance relative to the temperature of the water.
The heater claims to be for 1.5 gallon tanks, but in my 1.6 gallon tank, it reads 84 which is 2 higher than the max temperature a betta can handle.
61% appreciated its adjustable settings, but 39% found them limited.
The heater is not adjustable and not suitable for my 1.6 gallon tank. Additionally, it heated the water 2 higher than the claimed maximum temperature of 82 mentioned in the description.
Both heaters did not work and one of them malfunctioned, killing my daughter's fish.
The temperature fluctuations can be stressful for fish.
66% found it to be extremely durable, but 34% experienced a short lifespan.
The heater is great and takes up little to no space in my 1.5 gallon aquarium.
I was able to use the heater for 2.5 more gallons than its rating and it had no problems keeping up.
I experienced a burn on my finger while taking the aquarium heater out of the tank.
I need to clean both tanks more often due to increased algae growth caused by the water temperature.

70% found it easy to install, while 30% struggled with the process.
After placing the heater in the tank and plugging it in, I noticed that the fish started swimming around within half an hour, indicating that the installation was easy and effective.
I have three containers filled with water up to 80% and each container has this heater.
I bought two aquarium heaters/chillers but neither of them worked. One of them malfunctioned and killed my daughter's fish.
67% liked its quiet operation, but 33% found it too loud.
I recommend monitoring the temperature often if you have this heater in a smaller tank as it may be too hot.
64% praised for its built-in safety features, while 36% experienced a malfunction.
The heater stays put very well and has a low-profile, professional look.
The heater is safe to use as it senses the water temperature and turns on incrementally to maintain it, preventing tank overheating.
I have noticed that the water temperature is causing more algae and it needs to be cleaned more often.
The heaters are placed side by side and have different readings - 84F, 80F, and 81F.
72% praised for its precise temperature control, while 28% experienced fluctuations.
I keep the fish tank at the right temperature around 77 degrees with the heater and my five guppies love it.
The temperature of the tank fluctuates wildly, even when the ambient room temperature remains constant. It can be stressful for fish, so I have decided to look for a replacement.
The product description is misleading as it states the heater starts under 77 and stops at 82 degrees, but it actually starts heating at 74 and stops over 77 degrees.
The product is not working and the water temperature is below 76 degrees. I would appreciate a new working one to be sent.
