Review on YukiHalu Mini Submersible Aquarium Heater With Thermometer And Temperature Controller - 25W, 50W, 100W, Or 200W Options For 5-40 Gallon Fish Tanks by Lori Jordan

Revainrating 2 out of 5

25W is not sufficient for a 5gal, open-top tank.

Although an economical and compact tank heater, I have found that the 25W model is insufficient to reach the target temperature (72F) in my 5-gallon open-top tank. Ambient temperature in my house is about 60F in the colder months and it only manages to reach 69F. I am concerned that means the heater will continue to run while never reaching 72F.Additionally, I found the power cord to be fairly short.

Pros
  • External Temperature Controller, Never Wet Your Hands
Cons
  • The heater can get damaged by saltwater environments
