AquaClear 11182 First Impressions

"So far it seems great!"

I went ahead and went with the the larger 300W for my 45 gallon. Keeps the water consistent and it's easy to adjust! There is no protection from it banging on the glass tank. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. I would definitely recommend this product. This is a powerful heater that holds temperature very well. So when I first received it it didn't work and I was very disappointed.

AquaClear 11182 Final Thoughts

"That wasn't a good sign."

Those turned out to be a hit and miss. The heater protector was very heavy plastic and slim lined which is great. The heater is super thin and the reflective surface is interesting. The temperature lights up so it's very easy to read. You don't have to worry about wide temperature swings with this unit. Temperature is slightly off by running a little warmer. I am very happy with this purchase.

"I like this heater."

The heater is super thin and the reflective surface is interesting. Also were nice along the whole process. I used to try those other cheap heaters sold on amazon. The controller is easy to use, very accurate and reliable. The cover over the heating tubes is great, the turtles claws can't damage the tube. Product was received fast, works excellent! I adjusted the set temperature a little lower to be more in the range I wanted.

"Looks as advertised."

So far I like it setup was super easy. This is only day one though, so I shall keep an eye one it. The temperatures are pretty accurate. When i installed them, i let them sit in the tanks without power for 6-24 hours. Very easy to install and the adjustable temperature gauge is pretty accurate. The temperature difference was very minor. Seems to keep the temp n the tank fairly regular.

"Just perfect for my 1."

I'm in the process of setting up for tanks. This little heater is perfect; this is our third purchase of the same heater. This heater warmed it right up and now my Betta and guppies are more active. I like to keep it at 72 and from my thermometer it is reading at exactly 72. Product was received fast, works excellent! Those turned out to be a hit and miss. It would stick out of my 30 g wide tank if I were to put it vertical.

"Buy with confidence!"

Two inches above that is a waterline for maximum. It comes with a hanging kit and can be secured on the edge of the tank. Sometimes it gets outside of it's ability to cool but only within a few degrees. This has the best controller that I have found on the market. I was worried about the quality but I am thoroughly impressed with this heater! I have it set to 81F to get a 77F water temp. This product came in the nick of time!

You don't have to worry about wide temperature swings with this unit. The design is sleek and modern looking. I got this heater for my 55 gallon aquarium.

"Great product!"

I use a 50 for a 5 gal and a 10 gal tank. It took about an hour to reach 80f, which is fairly quick. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. This does a great job at regulating the temp in my 10 gallon. I wouldn't buy any other heater, unless one of these stops working. It took me a few days slowly turning the dial up to finally get it where I wanted. I recieved this product without the instructions or the added thermometer.
