Review on 100W/300W/500W/800W Submersible Aquarium Heater with Intelligent Temperature Probe and LED Display External Temperature Controller for Fish Tank 5-158 Gallons by Miriam Mendez

Revainrating 4 out of 5

Works as expected: fish and aquatic animals

My 75 gallon aquarium got to 69 degrees after my old heater failed. It only took 2 days to get it to 81. I increased it a few degrees a few times a day. It probably could have gotten him back to 81 a lot quicker, but I didn't want to put my fish in it. The product is well made and easy to use. I will update my review if anything changes. It works great so far.

Pros
  • Perfect for outdoor activities
Cons
  • Not bad, but...
