## Description

Product description

Review: 10/10 recommend! - I’ve bought this heater twice now, and at this point it’s easily my go-to for every aquarium I run. I actually have one in all of my tanks, and it’s been super reliable across the board. The digital LED controller is a huge upgrade compared to the older dial-style heaters—it makes setting and checking the temperature really simple and accurate. I also really like the automatic shut-off feature when it leaves the water. That gives me peace of mind, especially during water changes, because I don’t have to worry about it overheating or getting damaged. Heating performance has been solid too. It brings the tank up to temperature quickly and keeps it stable without constant fluctuations, which is exactly what you want for keeping fish healthy and stress-free. Build quality feels great, and installation was straightforward every time. No issues, no surprises—just works. Overall, this is one of those products I keep coming back to because it does exactly what it’s supposed to do, and does it well. Definitely recommend if you want a dependable heater for your aquarium.
Review: Affordable and reliable - I wanted to wait to leave a review. After 7 months it’s still going strong with my saltwater reef tank. Using it in my sump to keep my 90 gallon warm. Even during the dead of winter on the east coast when my teen left my door from the outside into my fish room open dropping the room temp to 40° this kept my tank at 76° (set point was 78°) and everything survived. Highly recommend and will be looking into another one for the 125 I’m currently building.

### ⭐⭐⭐⭐⭐ So far this has been perfect.
*by H***T on November 13, 2023*

It's supper easy to use. Very plug and play. I had read the reviews and seen a lot saying it was off 2 or 3 degrees but could test water and then set it accordingly. When I showed up I used 3 different digital thermometers and one manual mercury. All the digital had the same reading as the heater. And the manual was one degrees lower or less. Hard to tell if was .5 or 1.0. I ran a hot fire last and my tank was getting to hot as they are in the same room and I could see it's temperature going up..... it got to 82 before I had to start cooling the tank. When it drops down under the set temp it kicks on to 500ish wats and heats the tank rather quickly to 79. Cons.... I tried to set it horizontal and it started to alarm out almost instantly. The temperature read 98° almost instantly. I wanted to hide this behind rocks in the main tank instead of the sump. Stuck to the back wall sideways it would misread and alarm. Bummer as it would need to be sideways in my sump if I put it there also. Not enough to doc a star but disappointed. Also control cable is a little short. Not bad but it would be a little convenient if had another 12" In the end I believe most of the bad reviews of melting are user created. Like left on or removed from water before it had cooled.
