HITOP 50W Mini Adjustable Aquarium Heater: Digital Fish Tank Heater with Protective Cover and Controller for 5-30Gallon

I use this primarily to heat up my new water in my 60g container, which it took my 300w too long. This takes about 2 hrs to reach the desired temp of 82F from 63F.I think its coated with titanium and not made of it. higher chance of it being steel with a coat. price always dictates.As it is metal . it should last as i knock this about.what is a bit off is the heating element as it takes time to cool off, always raising then lowering my temp by 1F . fish dont seem to mind. but it is super quick to reach desired setting.I do believe for my purposes it will last. and that gives it my vote.2 thumbs up!!

I'm very impressed with the functionality and ease of use. One button control that's easy to use. I have it on a 125 gallon and it maintains the temperature easily. It is a little bulky in the display tank but it works. The suction cups seem to hold it firmly in place and it came with extra suction cups.

Worked well but my electric bill was pretty high using this heater. After I unplug it last month my bill cut down to half.

Works well in my 125 gallon. Have it by my spraybar and temps are staying consistent across the tank. The digital reading is off by 3 degrees - I have 3 separate thermometers all measuring the same. For example when this is set at 80 - the digital thermometers all read around 77 across the tank. Easy to compensate for the difference.Love that I can adjust the temps with an easy touch of a button - came in handy when I needed to up the tank temps due to ich. It was able to increase the tank to the higher temps needed and hold it there. Difficult for most single heaters in a 125.

If you don't keep it next to water flow. ( filter return to tank) temp rises and it over heats. But if you keep it where water flows by it works great

It came very fast delivery for #1 and easy to set up,just read 👍looks good in my tank. It's all so easy to Read the Temperature .when the lights are off .very happy with it 😊 so far 🙏hopefully it lasts long 😉If not I will get another one for you 😀

Finally a heater that works.. My diamondback terrapin is now swimming around all happy and trying to make “fetch” happen. You go Glen Coco.

I find water heaters for aquariums or pond are rarely accurate in temp setting compared to actual water temp. This heater is a high wattage and claims to heat >100 gallons. First the actual setting of the desired temps has to be done while unit is submerged ... then reading the digital face is difficult while trying to set. Making a new setting is very difficult and the instructions are not clear on how to do this. I finally managed to set this at 77 degrees F. This is a 100 gallon outdoor pond in so. Cal. Daytime temps are 75F+ with nighttime around 46F. The temp of the water after 24 hours is 68F. The heater shows the water temp is 77F and is therefore not heating as it is showing the desired water temp set has been reached, except it hasn't. A 9degF is a considerable difference. What happens if I adjust temp up, will it continue to have the 9deg difference or will it heat the water to the increased setting? I have asked for an explanation and I have been told this heater is not supposed to be used outdoors ... a missing fact when I was looking for a "heater for 100 gal pond" , then I got told to have a pump and filter ... which I do have already which I would have in an aquarium or pond!! I note that others have also commented on the set temp is way off to actual water temp after heating. I am very dissatisfied with the answers I have been given by the supplier as they have not answered the main fact that the temperatures shown are significantly off ... is it just this heater I have been sent or are all of them off?UPDATE: SOMEHOW THE TEMP SETTING HAS CHANGED WITHOUT MY INPUT AND IS SHOWING 33 DEGREES CELCIUS AND IS HEATING THE WATER WHICH IS NOW AT 77 DEGREES F. THE PROBLEM IS THAT 33 CELCIUS IS 91 FARENHEIT ....... HOW DID THAT HAPPEN!
