AQQA Final Thoughts

"Until the next time."

I got the 200W variant for my 54 gallon corner tank that's housing goldfish. I think it works well to not stand out like other heaters. Checked the accuracy of the heater with an infrared thermometer. You don't have to worry about wide temperature swings with this unit. I noticed my old hygger heater beginning to fail and my wife ordered this one. 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. I emailed the email it says to and told them. Would be great to be able to tune that to.

"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.

Also I like how it shows both the current temperature and the set temperature. I have 3 of the Fluval heaters, in various sizes. If the water runs low or air gets in the heater shuts off. I like how the heater is constructed. Very easy to install and the adjustable temperature gauge is pretty accurate. Will update my review if any changes occur.

It is a bonus that the heater is titanium. No biggie, but annoying nonetheless. I have a 10gallon tank that was at 72 degrees.
