Obscure Manual - Aquarium Heater & Cooler

I ordered this heater to replace a 25 watt Penn Plax heater that is no longer working. I've read the manual SEVERAL times and I still can't change the water heater from 82 degrees. I would like this heater more if I could understand h8w to change it. In addition, it is very large for a small aquarium. On the plus side, the LCD is easy to read and the on/off indicator is bright and easy to see.

Pros
  • Wide Temperature Range - Heater temperature can be adjusted between 20-34℃, 68-94°F. Suitable for fresh or marine water, it is excellent for many species of aquarium, fish and amphibious turtle.
Cons
  • The list will be long.

DON'T LOSE MONEY

Don't worry, the so-called heater doesn't work, this second heater didn't work either. There are currently 9 aquariums installed, I know a lot about heaters. I was trying to use this heater in a hospital aquarium that currently has 2 residents. WHERE the water should be 81, it's now below room temperature 72. These guys are already in trouble and don't need useless heating that refuses to work.

Pros
  • Easy View & Safe Setting - It's easy and safe to set the temperature with an external controller and the temperature is displayed on the heater's LED screen.
Cons
  • Band

Bad Bad Don't Buy The Best In Aquarium Heaters

This is incorrect for the 37 gallon tank just below the power supply. The first just stopped working. The second struggles to raise the temperature to process the tank. Poor heating, the temperature never matches my two thermometers, one front bottom left, one back top right, and they never match the heating and don't really match, it's probably 150w max. My fish room is also very well heated from the outside , so that the temperature does not have to be raised much. Find another article.

Pros
  • Durable Aquarium Heater - This aquarium heater is made of high quality thickened quartz glass, double-sealed material and advanced design to ensure safe operation. It has an explosion-proof function, and it is also shatterproof and waterproof.
Cons

DO NOT BUY POS Heater

The product came in a box with a broken seal and the label said 'New' but the case was cracked and the screen scratched like hell. I hesitate to turn it on, did it with care and the damn thing will never start heating the water. My tank is 70 degrees and the damn thing didn't light up or read that the water was 70 degrees (set it to 82). Trying to set the temperature is crazy because the instructions are vague but "seem" easy (until you try to set it). The product is complete junk. I don't know

Pros
  • Intelligent Temperature Control - It can keep the temperature constant at the set level because it automatically adjusts the heating power according to any water temperature fluctuation. So that it can avoid temperature mutation and protect the fish.
Cons
  • Lots of things
