hygger 500W 800W Aquarium Heater, Submersible Fish Tank Water Heater with External Color LED Digital...

hygger First Impressions

Excellent build quality.

Come on Fluval, expect better from you. I have only had minor problems with the suction cups. The bonus digital thermometer it came with has been super helpful, and is accurate. This is a great heater that is very easy to set up and program. All seem to vary between 1-2 degrees of each other which doesn't concern me much. But my guys don't read them and don't listen! Two inches above that is a waterline for maximum.
