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.

"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.

"Same suckers for years!"

--The heater itself is a bit shorter if your tank is a short one. Easy enough to let it run all the time. I emailed the email it says to and told them. When i installed them, i let them sit in the tanks without power for 6-24 hours. I have 3 of the Fluval heaters, in various sizes. They shipped us the upgraded version that also heats! The suction cups are large, high quality and seem to stick great.

"5 or even."

If the blue light is flashing it means the heater is not fully submersible. Well worth the money the first one I bought still works great. I use a 50 for a 5 gal and a 10 gal tank. I dont know, and havent tried just yet. I appreciate the exterior temp readout and control module. I tested it by unplugging and replugging it. I contacted the manufacturer and they sent me a new unit in less than a week!

"Pricing was good."

This is a powerful heater that holds temperature very well. I wouldn't buy any other heater, unless one of these stops working. After several weeks of running the heater. The line is there due to regulations in certain countries. Was very impressed with the quality of this heater. Also I like how it shows both the current temperature and the set temperature. I used to try those other cheap heaters sold on amazon.

"This is a quality heater."

Also I like how it shows both the current temperature and the set temperature. I have 3 of the Fluval heaters, in various sizes. If the water runs low or air gets in the heater shuts off. I like how the heater is constructed. Very easy to install and the adjustable temperature gauge is pretty accurate. Will update my review if any changes occur. I'm not a big fan of the big glass tubes.

"I would buy again."

The heater protector was very heavy plastic and slim lined which is great. Per my thermometers, they are all staying constant. If the water runs low or air gets in the heater shuts off. This heater works, but the dial it isn't very accurate. My fish likes to get close to it and he has never been hurt by it. They shipped us the upgraded version that also heats! It does blend well in some setups and may look bulky in others.

"It easy to set."

So far I like it setup was super easy. I hope these suction cups work very well. Sometimes it gets outside of it's ability to cool but only within a few degrees. The heater protector was very heavy plastic and slim lined which is great. You don't have to worry about wide temperature swings with this unit. It took about an hour to reach 80f, which is fairly quick. Also I like how it shows both the current temperature and the set temperature.

"5 gallons."

I have it set to 81F to get a 77F water temp. I dont know, and havent tried just yet. Easy enough to let it run all the time. The temperature gauge is fairly accurate in my 55 gallon tank. It took about an hour to reach 80f, which is fairly quick. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. It's only been set up for a month we'll see how well it does in a few months.

"Very pleased so far."

There is no protection from it banging on the glass tank. There is a misconception on the internet that the heater isn't fully submersible. --The cylinder or rod diameter is bigger. They shipped us the upgraded version that also heats! All seem to vary between 1-2 degrees of each other which doesn't concern me much. I like to keep it at 72 and from my thermometer it is reading at exactly 72. There is no protection from it banging on the glass tank.

I like to keep it at 72 and from my thermometer it is reading at exactly 72. I will definitely be buying another one for my other tanks at bigger one. I am very happy with this purchase. No biggie, but annoying nonetheless.

You don't have to worry about wide temperature swings with this unit. I was amazed how quickly I got to my temperature I need it 78 degrees. This has been in my fish tank for a few months now and it's been absolutely perfect! You don't have to worry about wide temperature swings with this unit. It is a bonus that the heater is titanium.

I went ahead and went with the the larger 300W for my 45 gallon. It comes with a hanging kit and can be secured on the edge of the tank. I got a hold of Amazon, who put me in touch with the seller. Very easy to install and the adjustable temperature gauge is pretty accurate. Two inches above that is a waterline for maximum. This is a great heater that is very easy to set up and program. The temperature difference was very minor.

At this time I highly recommend this product. I wouldn't buy any other heater, unless one of these stops working. The controller is easy to use, very accurate and reliable. Personally for me the housing doesn't bother me. So if you set it to 78 degrees, the heater will not kick on until it reads 76. --Temperature adjustment labeling is on top rather than on the rod.

I noticed my old hygger heater beginning to fail and my wife ordered this one. The heater is super thin and the reflective surface is interesting. After several weeks of running the heater. Come on Fluval, expect better from you. Takes a little while to drop the temps if it is hot in the garage. We wish the controls were available in Farenheit also to make things a little easier.
