Very nice and thin heater. Has been maintaining my desired exactly.
wow, best heater I have come across
This aquarium heater is the best heater I’ve ever used. Keeps consistent water temperature within about .6 degrees. It’s also very easy to change the temperature desired with the easy to use button on top of the heater. No more using a difficult to turn dial like other heaters use. I also like that it’s not made of glass and it’s flat design is a plus in aquarium placement.
I am very satisfied with my recent purchase of 3 Cobalt Neo-Therm aquarium heaters. Due to their sleek, flat design and ease of operation, they are one of the BEST heaters available. To adjust the temperature, you simply click the button on top of the heater, which is easy to access WITHOUT having to take it out of the water. It can easily be hidden by tall aquarium plants due to the fact that it hangs vertically in the tank, which is very appealing to the aquascaper. Despite the high price, I feel that these heaters are good investment, and hope they will last for many years!
Great heater! So far so good!
I am, so far, happy with this product. I am a little disheartened though at the way it was packed. A $90 heater! It was thrown i the delivery box and was obviously knocked around quite a bit. I thought it was a return that was shipped to me. The box was a mess. I was considering sending it back, but the unit was intact and the electrical wire appeared to be not to have been unravilled, so I took a chance. Sorry, I think $90 is a bit expensive to be handled so negligently. May not be a lot of money to someone else, but it is to me.
My reef tank has never been at a more consistent temp than with this heater. I had read a lot of reviews but I’ve had this heater for about 2 weeks not and my temp has even fluctuated a degree. Consistent 79.2. I run a 13.5gal and the 75watt is perfect.
I have become a huge fan of this new aquarium heater and have replaced all my others. I have lost fish when the glass tube heaters inevitably fail and overheat or stop working. These keep my tanks at a steady temperature, and their slim flat shape and black color look great in the tank. Modern Aquarium got my order to me quickly and safely.
