🐠 GMsound Submersible Fish Tank Heater with Thermostat - Ideal Aquarium Water Heater Review

After looking at many aquarium heaters on the internet, I decided on the GMsound aquarium heater. I chose this one based on the features I was looking for in an aquarium heater. The thermostat is adjustable and has a light so I know when it's heating up. The kit also included a thermometer for the tank and detailed instructions. Thanks for a great product!

I bought a 100 watt heater for my 40 gallon tank. The website description says it works up to 45 gallons, but that doesn't apply to mine. It's been sitting in my tank for 4 days now and I've turned it full on and it still doesn't get above 72 degrees Fahrenheit (which is just a tad warmer than the air temp in my house so that hardly tells me it ever gets hotter). is working). general).

As others have said, it seems to be 10 degrees off (82=72). Once you figure out how to compensate for this, you're good to go. The suction cups are also average (one sticks, the other doesn't), but the one that works seems to hold it in place. For the price, it's probably closer to 3.5 stars than 3, but such a large variance in temperature can definitely be an issue. Hope this review helped.
