"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.

"So far so good."

This is a great heater that is very easy to set up and program. If the water runs low or air gets in the heater shuts off. This heater warmed it right up and now my Betta and guppies are more active. I dont know, and havent tried just yet. I'm not a big fan of the big glass tubes. And I get to keep the first one I bought! I got this heater for my 55 gallon aquarium.

"Seems very well built."

This heater is NOT fully submersible. It took me a few days slowly turning the dial up to finally get it where I wanted. Keeps the water consistent and it's easy to adjust! And kids love pushing all sorts of buttons. Will update my review if any changes occur. No biggie, but annoying nonetheless. It's only been set up for a month we'll see how well it does in a few months.

"Looks as advertised."

I got a hold of Amazon, who put me in touch with the seller. Once attached to the tank wall I've had no issues with it coming off. I adjusted the set temperature a little lower to be more in the range I wanted. --Temperature adjustment labeling is on top rather than on the rod. I had a thermometer on opposite side of tank and the heater was dead on true. --The cylinder or rod diameter is bigger. But my guys don't read them and don't listen!

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.

"The seller was wonderful."

So when I first received it it didn't work and I was very disappointed. Was very impressed with the quality of this heater. The red light means it's off, blue light means the temperature is constant. Temperature is slightly off by running a little warmer. I have 3 of the Fluval heaters, in various sizes. I wouldn't buy any other heater, unless one of these stops working. For Discus you need warm and accurate heater and this seems to do the trick.

  • Eheim Thermocontrol e100 Heater
  • With the EHEIM thermocontrol-e heating element your fish get the right temperature even more precisely - in every aquarium. The EHEIM thermocontrol aquarium control heater is a further development of the legendary heating element and thermocontrol-e is the latest electronically controlled variant. The obvious ideas are often the best. This also applies to the aquarium heating element. It is simply hung in the water and heats it up. The principle is the same as it was decades ago. But in the meantime the EHEIM controller heater has become an ultra-modern thermal device. The temperature can be set precisely from 68°F to 89°F. It is measured even more precisely and kept more constant by the electronics with a control accuracy of 0. 5 °C. The heat is kept constant with an LED that indicates the heating function. The coating on the heater is made of special laboratory glass that increases the heating surface, serves as a heat shield and ensures even heat emission. There are no cracks and hairline cracks through which condensation water could pass. It is impact resistant. And even extreme temperature fluctuations, such as those that may occur during water changes, do not affect this glass. The heater is absolutely waterproof, can be fully immersed, has a dry run protection (Thermo Safety Control) and is suitable for fresh and marine water.

"The FreeSea is amazing."

I confirm it with my cooking digital probe thermometer. Just be careful and keep an eye on your temp settings when you have kids over! It took me only two tries to get it to the correct temperature. This has been in my fish tank for a few months now and it's been absolutely perfect! Very easy to install and the adjustable temperature gauge is pretty accurate. I think it works well to not stand out like other heaters. I got a hold of Amazon, who put me in touch with the seller.

Per my thermometers, they are all staying constant. I will be ordering more of these in the future. My marina heater takes a few hours. All seem to vary between 1-2 degrees of each other which doesn't concern me much. The suction cups are large, high quality and seem to stick great.
