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.

"6 gallon tank."

I went ahead and went with the the larger 300W for my 45 gallon. The suction cups are large, high quality and seem to stick great. If the water runs low or air gets in the heater shuts off.

I left seller feedback yesterday but have yet to hear from the seller.

"6 gallon tank."

I had a thermometer on opposite side of tank and the heater was dead on true. The bonus digital thermometer it came with has been super helpful, and is accurate. Sometimes it gets outside of it's ability to cool but only within a few degrees. They shipped us the upgraded version that also heats! I love the heater otherwise, but I'm afraid some water has gotten inside the heater. For Discus you need warm and accurate heater and this seems to do the trick. Those turned out to be a hit and miss.

"It easy to set."

Seems to keep the temp n the tank fairly regular. Maintains it well except when the weather is already warm then it over heats it. Also I like how it shows both the current temperature and the set temperature. I contacted the manufacturer and they sent me a new unit in less than a week! The temperatures are pretty accurate. Am a totally sold customer and would recommend them to anybody! I think it works well to not stand out like other heaters.

"They contacted me."

You program it for temperature you want your tank to be. We received the chiller promptly and put it into use. I hope these suction cups work very well. I used to try those other cheap heaters sold on amazon. Seems to keep the temp n the tank fairly regular. The red light means it's off, blue light means the temperature is constant. The cover over the heating tubes is great, the turtles claws can't damage the tube.

"What a long."

It just cycles through to 93f and starts over. Bought it as a chiller for the k40 CO2 laser. I had a thermometer on opposite side of tank and the heater was dead on true. This has the best controller that I have found on the market. The cover over the heating tubes is great, the turtles claws can't damage the tube. It does blend well in some setups and may look bulky in others. After several weeks of running the heater.
