500W Aquarium Heater Submersible 500 Watt Titanium Fish Tank Heater with External Temperature Controller for 60 Gallon to 95 Gallon Tank

This heater just works, no adjusting. It just keeps on working and tells me the temp of the water by walking by and looking at its LED read out. Best for your money! And heats too.

I got this thinking it was same as one I had 5 years. But nope, quality fell off a cliff. Worked ok, not great for 10 days, then quit heating. Took 2 days to raise 100gal indoor tank by 3 degrees 73 to 76. I think it held at 76 once there, until it didn't and wont heat. Tried a few days and couldn't get it to heat. Returned after 2 weeks

Well built, stealthy. Easy to adjust temperature via the power cord. Works perfect in my 90 gal tank with tropical fish. LED numbers and on/off light are perfectly visible from front of tank. Good purchase.

This is a very efficient aquarium heater. It worked right out of the box.

This heater works really well—heats the tank quickly and keeps the temperature stable, which is exactly what I needed. It’s easy to use and the display is clear and accurate. However, the downside is longevity. I’ve gone through two of these now, and neither lasted more than a year. For the price, I expected better durability.If you need something that works well short-term, it’s great—but don’t count on it for the long haul.

Dear seller,Upon awaking this morning I find my aquarium has tremendous heat emanating from it, the water is cloudy and all my fishes are dead as well as plants appear to be in distress. Now my tank is DEAD. I trusted you and your heater and now have lost my entire investment of fishes, supplies and the seal on the aquarium is now subject to possible leakage. I am requesting a full refund for the heater, financial losses totaling $225 (USA), due to the loss of fishes and plants and the horrible emotional stress I have seeing all my work and pleasure gone due to your malfunctioning heater. I now must start all over again and I am saddened and upset. Please see the pictures attached showing an E2 error, cloudy tank and dead fishes.

Great heater and easy to use. Really like having the love temp reading and ease of adjustment.. eliminating the guess work of the traditional know.

Great Product and Easy to Use.Looks like a Quality Item.Solid!
