Review on 🐠 Submersible Aquarium Heater: Adjustable Temperature Thermostat for Various Gallon Fish Tanks - 50W, 100W, 200W, or 300W by Darla Wilmoth

I just installed this 100 watt heater in my 29 gallon tank about 30 minutes ago. 200 watts is the recommended model for this tank size, but I figured since this is a goldfish tank (a cold water creature) I just wanted to keep the temperature at 68 degrees or higher. I wouldn't buy a heater at all if I didn't have slugs to keep the jar clean and I think 68 is the lowest temp slugs can handle. Goldfish are fine as long as they aren't frozen in a block of ice. The device looks good as expected. Narrower than the old heater it replaces. The setting has a dainty orange display that shows the set temperature. The suction cups are very strong. I actually had a lot of trouble moving the heater after realizing I installed it sideways. My only real complaint is the red power indicator, which shows when the heat is actually active and the heat can't be seen from any angle other than fully. I think that's a good choice, but be mindful of the power you need for your tank size and the pace your critters need. The Chinese class is fun. I don't understand why they don't go to a native English speaker for advice on grammar and word choice? Might be a good consulting deal for someone.
