Review on 🐠 SZELAM Aquarium Heater: Upgraded 100/300W Fish Tank Heater with External Controller and Split Temperature Probe - Auto Shut Off, Ideal for Betta Fish and Turtle Tanks by Natasha Davis

I have 3 red earworms in my 29 gallon aquarium. I use a ZooMed TC-32 filter and a 6" aeration stone to purify the water. I'm very happy with how it looks and even more so with its capabilities. This heater is near the inlet of my filter, and I have a separate thermometer on the other side of my tank. The temperature on the reader (through a probe attached to the heater) is only 1-2 degrees different compared to the thermometer. The only minor complaint is that the suction cups don't stick like I'd like, but that might be my fault. - I attached them underwater. I'll be re-installing it on a drywall soon after draining the tank and this might fix the problem. All in all I would definitely recommend it. The packaging is in a cardboard box and is sufficient to prevent breakage; the cables are in two parts, which makes it easy to mount the panel on a large tank from the opposite side as well (one line from the wall to the panel, one from the panel to the heater); Made in China
