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.

"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.
