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.

"Highly recommended."

I dont know, and havent tried just yet. Also were nice along the whole process. The line is there due to regulations in certain countries. Takes a little while to drop the temps if it is hot in the garage. But I am single and don't have to worry about this. After several weeks of running the heater. I think it works well to not stand out like other heaters.

"I like this heater."

The temperatures are pretty accurate. The suction cups are large, high quality and seem to stick great. This is only day one though, so I shall keep an eye one it. It would stick out of my 30 g wide tank if I were to put it vertical. I got this heater for my 55 gallon aquarium. Well I bought a second one took me only one trying to get the right temperature. The cover over the heating tubes is great, the turtles claws can't damage the tube.

"Peace out."

I would definitely recommend this product. The temperatures are pretty accurate. If the blue light is flashing it means the heater is not fully submersible. Sometimes it gets outside of it's ability to cool but only within a few degrees. I got the 200W variant for my 54 gallon corner tank that's housing goldfish. I dont know, and havent tried just yet. It does blend well in some setups and may look bulky in others.

"I got the 100 watt one."

Or better yet, conceal it to the back corner. They promptly fixed the issue without any delays or drama. I like to keep it at 72 and from my thermometer it is reading at exactly 72. It just cycles through to 93f and starts over. Come on Fluval, expect better from you. This is a powerful heater that holds temperature very well. I recieved this product without the instructions or the added thermometer.

"Until the next time."

So when I first received it it didn't work and I was very disappointed. The heater is super thin and the reflective surface is interesting. Two inches above that is a waterline for maximum. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. So when I first received it it didn't work and I was very disappointed. Per my thermometers, they are all staying constant. I will definitely be buying another one for my other tanks at bigger one.

"That wasn't a good sign."

I have a 10gallon tank that was at 72 degrees. But I am single and don't have to worry about this. 210 gallon ones and one 90 gallon bow front tank. Easy to read the temp and know exactly how warm the water is. This heater warmed it right up and now my Betta and guppies are more active. The temperature lights up so it's very easy to read. I noticed my old hygger heater beginning to fail and my wife ordered this one.

"9 degrees."

I had a thermometer on opposite side of tank and the heater was dead on true. I left seller feedback yesterday but have yet to hear from the seller. The bonus digital thermometer it came with has been super helpful, and is accurate. I got the 200W variant for my 54 gallon corner tank that's housing goldfish. I'm not a big fan of the big glass tubes. The design is sleek and modern looking. Also I like how it shows both the current temperature and the set temperature.

"Works just as advertised!"

This is a great heater that is very easy to set up and program. It is a bonus that the heater is titanium. Beware, but we are hoping for a good outcome! When i installed them, i let them sit in the tanks without power for 6-24 hours. It's only been set up for a month we'll see how well it does in a few months. I appreciate the exterior temp readout and control module. I got this heater for my 55 gallon aquarium.
