HiTauingAquarium Heater, 50W/100W/300W/500W Submersible Fish Tank Heater with Over-Temperature Protection and Automatic Power-Off When Leaving Water for Saltwater and Freshwater

"I couldn’t be happier with this aquarium heater! It’s reliable, efficient, and maintains a consistent temperature, which is so important for the well-being of my fish. The adjustable thermostat is easy to use, allowing me to fine-tune the temperature to exactly what my tank needs. I’ve been using it for a few months now, and it has kept the water temperature perfectly stable, even during colder days.What really impressed me was how quickly it brought the tank to the desired temperature after setup. The build quality feels solid, and the indicator light is a nice touch, letting me know when it's actively heating. The compact design fits seamlessly into my tank without being too obtrusive.Overall, this heater has made tank maintenance much easier, and my fish are thriving in their warm, comfortable environment. Highly recommended for anyone looking for a reliable and affordable aquarium heater!"

Works well and has temperature indicator for heating and when heated good price fast delivery easy to fit

Plug it in, set the temperature (Fahrenheit) and off you go. Worked really quick bringing my aquarium up to the required temperature. If there was a downside then guage was in Fahrenheit & instructions in German, but there's pictures and a little Google for the conversion chart to centigrade. Overall I like it and it does it's job.

Only in tank for 2 days and it seems ok temperature holding at set amount , and good that one can see both set and actual temperatures although trang that the display is so blurred

I have tried so many heaters over the years, and this by far the best, and relatively well priced to.Instructions are ludicrously simple, even my 7 year old could figure it out (if you need to switch between Celsius and Fahrenheit, simply hold the button - as it even says in description).I only have a small 45l tank, but this has kept the temperature regular since I purchased.As the instructions state, do not leave this switched on when you remove from tank to clean, this is a really silly thing to do. Simply unplug, clean your tank, change your water etc, reintroduce to tank, and when full again, turn it back on, not difficult.NB: when unplugged, the heater does revert back to factory settings, so you will need to press the button a handful of times to get it back to your setting.The only time this could present a problem is if you're a regular holidaymaker and there's a power cut, as it will reset to factory setting. However, I personally check my temperature on the big digital display daily, and it takes literally a second, so for day to day use, this would never present a problem.All in all, for £20, it's great 👍🏻

I purchased this to replace a a cheaper one that failed within a week. SO far so good. I have installed it in my tank. Really easy set up and instructions, the external themometer and control is great. My only complaint, and as mentioned in other reviews is that the display is blurred because of the frosted plastic that covers it. I don't think this can be removed without the display getting damamged. you can make it out but it's not very easy. The photo does make it look worse than it is though.

Ok I now run 10+ of these in my tanks and there perfect can't fault them and accurate too.

So far so good. I've seen a few negative reviews mentioning that the temperature reads in fahrenheit, I just thought I'd mention you can hold the button down for a few seconds to switch to celcius. Hope that helps.

Is great works perfectly for my 75 gallon turtle 🐢 tank. I purchased the 500W.At first shows temperature 🌡adjustment very quickly but the water is still cold. Give it more time and I can feel the water with my hand and is already warm. Turtles love it they feel more alive .

Compre el de 500w y funciona muy bien calienta el agua muy rapido y el termostato tambien funciona al 100%, cuando baja el nivel de agua se detiene en automatico el calentador llevo 2 meses y sigue funcionando al 100%.
