The graphic readout of actual temperature settings is a terrific aid. So many aquarium heaters are "guess the setting and hope it's right." This one lets you see where you have it set, and has a visible LED indicator for when the heat is actually on. My house is on the cool side, but the 100 watt heater holds an even temperature in a 20 gallon tank without being on all the time. The plastic shield to prevent direct contact of fish with the heater tube is also a good feature.
I would recommend this to a friend!

Review 2 for Sera Aquarium Heater
PostedOctober 4, 2012
from Janesville, WI
This heater does exactly what it is supposed to do. It maintains my turtle tank at just the right temps. I really like the way you can adjust the temps right on the heater itself (but still keep a thermometer in there and check it daily!) This item was cheaper than the other heaters, and personally I like it better.
The Sera heaters are very well designed and reasonably price. I like the fact that it is easy to determine whether you are raising or lowering the temp by the temp lettering on the front. This may sound obvious but Ive used some brands where the symbols made no sense and you could not easily determine what way to turn the dial. Also the heater guard is a huge plus if you have fish that could burn themselves by resting on it, like plecos and bichirs. It also protects it against large boisterous chiclids. Ive had no problems with mine not keeping temp or skyrocketing the temp. It has worked well for quite a long time now. Very happy to see Petco carrying this item. Very high quality product for a reasonable price.
