Orlushy Submersible Aquarium Heater, Adjustable Fish Tahk Heater with Free Thermometer Suitable for Marine Saltwater and Freshwater

Living in Central Florida, you don't always think about extreme cold, but this past winter threw us some serious freezing temperatures. I bought this Orlushy submersible heater specifically to ensure my turtles didn't freeze when the indoor temps plummeted, and it performed beautifully. Why It’s Great for Turtle Tanks: Accurate Temperature Control: The dial adjustment is very straightforward to set. I monitored it closely with a separate thermometer, and the heater successfully kept the water at a stable, safe temperature despite the room around it getting quite cold. Turtle-Proof Build Quality: Turtles are notoriously clumsy and love to rearrange their tanks. Because this is made from thick, durable quartz glass, I didn't have to worry about my turtles cracking it or hurting themselves when bumping past it. Strong Suction Cups: The included suction cups actually stay anchored to the glass. Anyone with turtles knows they love to push equipment around, but this stayed firmly in place. Setup and Usability: It is fully submersible and easy to position. The power cord has a decent length, which made routing it to my surge protector simple. The indicator light is a great touch—you can see at a glance when it is actively heating versus when it has reached its target temperature and is idling. A Quick Tip for Future Buyers: Make sure you unplug the heater and let it cool down for about 10–15 minutes before you do water changes. Exposing a hot glass heater to cooler air or fresh water during a tank cleaning can cause the glass to crack (true for any aquarium heater!). The Bottom Line: This heater kept my turtles warm, safe, and active during a rough winter stretch. It is affordable, highly adjustable, and rugged enough for aquatic.

It’s been seven months since I’ve bought this heater it’s had been keeping the temperature pretty good and it even tho it does hover at 72-73.5 degrees Fahrenheit I have this way because my dojo pond loach’s have to have water below 80 degrees Fahrenheit or they will experience fungal infections and ich infections there a cold water fish used to cooler temperatures somewhat similar to gold fish which are actually a cold water fish and I have a albino mini pleco algae eater some people would call it measuring in at 5 inches last time I checked and the pleco’s like temperatures in the early 70’s and early 80’s 72-82 degrees Fahrenheit is a lil bit warmer but not too much so 72 is the appropriate temperature and the Cory’s like warmer temperatures as well hovering in at early 70’s to the early 80’s 72-82 degrees Fahrenheit so to keep everyone happy or at least satisfied I keep it at 72 degrees Fahrenheit and even this it does go up a few degrees that’s fine as long as it doesn’t go below past 79 degrees Fahrenheit that fine but let’s get into the heart of the subject:how long will this cheap heater last?🤔 well for the last seven months it’s held up pretty well so I’ll eyeball it five eight years approximately not sure like I said “eyeballing” it.subject2safety well it’s hasn’t made my tank become a boiling pot of loach food so that’s a plus and it hasn’t burnt up,melted, exploded,glass or heater either or shattered,hasn’t,stopped working,cord or heater electrocuted the fish and hasn’t busted the tank which is 35 gallon bowfront aquarium to pieces like a ticking time bomb and thickness of this cheap heater well it seems to be the last time I put it in and also had felt it which I touched it because I was trying to see if it was working yes it is still working and I have three thermometers on the tank one inside of the tank and reads the temperature outside the tank it’s the one that it comes with and this is not gonna blow up in my hands or fish tank question NO it’s not gonna be so cheap that’s it’s gonna be like a cracker this if you ask me is 4th or 5th in the top five list of best heaters on the aquariumist market 1st being eheim 2nd fluval 3rd being probably United because I searched it up and so….any way fourth being I guess yes orlushy brand and fifth I guess because my mother’s tetra fish heater didn’t stop working or melt I’ll put Tetra in at 5th place because well that’s what I’ve SOMEWHAT have experience on anyway great heater highly recommended and will be buying another one of this or another variant if this brand this brand has really surprised me yet….but for now yes great heater Godbless!

Have a 30 gal tank. It works great. It discreet in the corner. It doesn’t take away from the look of the tank

This size this power consumption aquarium heater itself are great , so far working perfectly, temperature control and adjustment are great , the price tag for the unit are very good compared to the other majors brand in the market, but the only one problem is the digital thermometer come with it , temperature show kind very tricky, set 80f but the thermometer show 85f! Then I have to buy a new thermometer

Heated my tank very well. It was very easy to put together and use.

Put in inside my 75 gallon (filled up about half way) for my red eared slider turtles. Works really well in keeping the water nice and warm for them.

Can't beat the price. Works good so far. It's hooked up to an Inkbird controller, so if it sticks on its not cooking anything.

First on3 the glass was completely shattered. Ordered a replacement, got it installed, after it sat in the tank for 24 hours I turned it on and set to 81 F I just came home and the tank is at 87 F and the heater is still heating. Not good at all. Luckily I have no fish in there yet, but thanks for cooking all my beneficial bacteria. Appreciate that, Orlushy. I cant recommend buying something with such a wild swing in temperature, thats a great way to kill a tank. EDIT: After checking with other thermometers, it appears that the digital thermometer is also about 5 degrees off, so maybe a 3 degree swing in actual set temp, still not sure how I feel about this heater, and alot of air bubbles accumulating on the outside, it just feel so sketchy, haven't decided if I'll leave it in or skip the risk

Best heather I have bought and I have tried many. The temperature control look knob is easy to adjust and works smoothly. The overall quality is great. The glass casing his quite thick and sturdy. Easy to adjust and precise. The thermometer supplied with the heater is also excellent. Great deal, i highly recommend.

Es lo que esperaba

I've been using this for about 4 months. The only complaints I have is there seems to be some evidence of scorching from the heating rod inside and the clips cannot be placed around the glass so it hangs oddly. Other than that it works perfectly. Maintains the heat settings and it looks good

It's good value for the money and heats my 20gallon tank no problem. It isn't 100% accurate though and seems to be off by about 2 to 3 degrees when using the nob to set the temperature. No matter, it came with a thermostat so I can always adjust the temperature accordingly. I'd recommend it.

It explained in the ad, that it held the temperature well, but the temperature you set it to, might be off by a few degrees, and then you adjust it. I seldom see this kind of honesty in advertising. My problem was the lowest temperature you can set it for is 68 degree F. Which is fine, as that is the temperature I wanted. Unfortunately, it kept the temp between 69.5 and 70, so there was no way to lower it. But, hey, I knew the risk going in. I can live with 70, if I have to.
