AQUATOP 200W Digital Heater with External Control - Fully Submersible for Fish Tanks Up to 50 Gallons, 68-93F Adjustable Temperature Range, Fresh & Saltwater Use, Aquarium Heaters, EX-200

Great delivery Amazon is awesome except the fact that all lives matter. I love all people and I’m not white or black wish All lives matter.

THESE HEATERS WORK WELL FOR ME....PRETTY ACCURATE. I LIKE THE DIGITAL READOUT

I used it in my 75 gallon saltwater tank & it raised the water temperature 5 degrees in a mat of 10 min....I'm very satisfied

First one that came didn't work, but at least looked good :) . I asked for replacement. Second one came completely broken. Sent it back, requested money

This heater work, but they are about 1* off on the actual temp, also the cord to the control is quite short.

Looks great, works great, and after a couple of months still works, which is better than some I've purchased. It also looks very nice.

Came in on time and looks amazing in my reef tank!

Google Aquatop Warranty and find: Note: All sales from Amazon and Ebay (regardless of seller) do not qualify for any warranty coverage. Please see the Where To Buy section for more information. The heater worked but would allow for swings in temperature of six to eight degrees. I purchased a 300W for a 29 gallon tank so one could make the argument that once the heater turned on it shot the water temp up so fast that when it self regulated and turned off the element was still hot and raising the temperature. However, most frustrating was when water temp was reading much lower than the setting but the heater would not turn on. Learned my lesson and will go with heaters with warranty in the future.
