Sobre este artículo

  • Fast Heating with Durable & Safe Design – The aquarium heater is made of explosion-resistant quartz glass and high-temperature resistant nickel-chromium for quick heat transfer and reliable performance in both saltwater and freshwater tanks. Dual sensor probes provide more accurate temperature monitoring, while the PC plastic protective cover prevents direct contact, ensuring your fish stay safe from burns.
  • Easy Operation with External Controller – The submersible fish tank heater comes with a convenient external controller for easy and precise temperature adjustment. Press the “SET” button to enter the temperature setting mode, and each press increases the set temperature by 1°F/1°C within the 59°F–93°F (15°C–34°C) range. Press and hold for 5 seconds to switch between Fahrenheit and Celsius.
  • Overheating & Dry-Run Protection – The fish tank heater will automatically shut off when the water temp reaches set temp. If the temp rises rapidly 3°F/3°C higher than set temp , the heater will stop heating immediately and a flashing alert will appear on the controller. When the heating rod is exposed more than 1 inch above water, an “E0” error code appears and heating stops. The protection systerm prevents overheating and dry burn, keeping your fish safe
  • Intelligent Automatic Heating – The AQQA aquarium heater adopts automatic thermostatic control. It stops heating when the water reaches the set temperature and automatically restarts when the temperature drops 2°C/°F below the set point. The memory function retains your settings after a power outage, making it more convenient to unplug the power cord for water changes.
  • Usage Instructions – Always fully submerge the aquarium heater in water before plugging it in, and ensure proper water circulation in the tank. After turning it off, allow the heater to cool in the water for 15–30 minutes to prevent residual heat from damaging the cover. Following these safety tips helps extend the lifespan of your fish heater. For any issues, feel free to contact us

Good heater

This is working great in my bait tank. Its a 180 gallon tote with a 30 gallon sump. It has been keeping it at 60 degrees so far and my bait is lively. I am building a second system and will buy a second heater for it, if I even need one. This one is very good. Read more

Excellent for my outdoor turtle pond

Better than I expected. I bought the heater for my outdoor turtle pond (125 gallons). I normally do not need a heater because I am located in FL and the water stays warm enough, but because of the harsh winter this year and I no longer have an indoor setup for my two turtles, I needed one. I specifically chose this one because of the adjustable thermostat and the plastic casing. All other “heaters” that I could find that were rated for outdoor use were de-icers and you can’t adjust the temperature. I highly recommend this one. Read more

GREAT BUY!

It was recommended to get 2 smaller heaters to evenly distribute heat in my 125 gallon tank instead of just one heater. I decided to get just one 1000W anyway. Glad I did. It is set on 78 and my tank water always reads 77.6-78 when I check it with a separate thermometer. It is spot on. Highly recommend! Read more

Strong heater but is quite large. Would be nice it had also a down temperature button instead of having to press the adjustment button 30 times to cycle through it Read more

Consistent temperature.

So far so good. Keeping the tank within one degree of set temp consistently. Love the control display too. Good value. 500W for the price of most 300W heaters. Excellent buy…so far. Read more
