  • 1 Dual temperature control system: one chip with two independent heating systems. When the temperature control system of one heating rod fails, the temperature control system of the other rod can continue to work, reducing the occurrence of frozen fish in the fish tank caused by damage to the heating rod, and ensuring the constant temperature of the fish tank
  • 2 Heating speed is controllable: the two heating tubes have independent temperature control, and the temperature control range is: 64-93℉. The heating rod is evenly wound with 20 nickel-chromium electric heating wires, dissipating heat evenly at 360°. The heating speed and power can be controlled by individually adjusting the temperature of each rod
  • 3 Easy to operate, the full immersion heater is equipped with three suction cups, which can be firmly installed in every corner of the fish tank; the outer shell can be slid away, making cleaning more convenient; the temperature can be adjusted by directly rotating the top knob; the sealed waterproof plastic can protect the internal chip. Improved durability
  • 4 Accurate temperature control: There are two sets of temperature measurement systems with built-in dual temperature probes to monitor the current water temperature in real time. When the detection reaches the set temperature, it stops heating and starts heating when it is lower than the set temperature. The temperature control error can be controlled within ±1 Within ℉
  • 5 Suitable for seawater and freshwater fish tanks, fighting fish tanks, turtle tanks, etc. 600W is suitable for 66-132 gallon fish tanks, and 800W is suitable for 80-220 gallon fish tanks. When installing, please completely submerge it with water and do not place it on sand and gravel

I've been using this heater on an outdoor Koi tank. It worked very well this winter when the outside temps got into the 20's. This heater kept the Koi tank above 70F. Very good heater.

I have these set up on my 135g saltwater reef tank one set at 79 other one 76 so if one fails other one will kick on. Very reliable readings

I just unboxed the heater and it does not have an indicator light to show when it's on. I will update my review when I can confirm it is working and can maintain temperature. Other than that, it fits nicely in my sump and was easy to set the temp.

The only reason I give it 4 stars and not 5 is because I currently have little Senegal bichirs that are about 3.5 inches long and one of them was going in to the space in the heaters cover and just chillin inside of it. I had to wrap the heater in some netting to cover the gaps so it would stop going in there. I feel like it’s more my fault than anything just because this is something I should’ve thought of before buying it. Luckily nothing happened to the bichir but it was scary lol. Other than that I do like the heater. It does the job, I like how it looks and I like how easy it is to use.If you have little fish or plan to get little ones that like to hide in small spaces be mindful of the gaps in the heaters cover.

This water heater is really nice for my 75 gallon tank and works great. The temperature is adjustable and doesn't take much space which is amazing. The fish in my tank seem to love it as well! Highly recommended for heating up the tank during the colder months!

I have had 2 fish die because of getting stuck in this heater.. a full grown Cory and a sub-adult angelfish. I am now looking for a different heater so I don't loose more pets.~Update~ The seller reached out to me and offered a full refund for the item, which was processed the next day. I am giving them an extra star for good customer service.
