How many watts should I need for a 10 gallon?
Answer by ChewyOct 24, 2019
Please refer to the picture chart below.

can the 50 watt be safely used in a 3 gallon fish tank?
Answer by ChewyMar 21, 2019
The 50 watt can be used in 3 gallon tanks and tanks up to 20-gallons. To ensure it will fit, compare the dimensions of your tank to the measurements of the heater which are 1.375 x 1.375 x 8.75 inches.

Does this have a built in thermostat to make sure the temperature is constant
Answer by ChewySep 12, 2019
This heater features a precise temperature dial from 68°F to 88°F which allows for complete control of aquatic climate within a 1-degree difference. It does not include a built in thermometer and will need to be purchased separately.

can I use two 50watt heater in my 20g tank?
Answer by ChewyApr 03, 2021
The 50w heater is rated for tanks up to 20 gallons. If you choose to use (2) 50w heaters or even a 100w heater, there wouldn’t be any issue. Just be sure when using 2 heaters, have them on opposite ends of eachother, not close together.

Does not last

Horrible! I had the exact same one which lasted 3 yrs. This one 4 months. They are useless as the bulbs that die within a month that run $35. What happened to quality control and standing by a product?!

Very disappointed

I opened the box, put this heater in my tank, and the next day it was full of brown stuff and water. Very clearly leaked and now it's ruined. My tank water is cold and all my snails are closed.

Poor Product, Good Customer Service

This heater died after a day of use. It wouldn't turn on at all. I reached out to Chewy and they took care of it.

would recommend 100%

I have this heater in my 75 gallon for my cichlids and my large pleco. The thing I love the most is how you can adjust the temperature you want and the light indicator that comes on to let you know it’s heating the water. In my opinion heaters like these are a big game changer for fish caretakers.

Didn't work

I had this in my 10 gallon tank that was cycling for a month and a half and it didn't heat it up once. It stayed on for about a minute and then it would shut off.

Such a sturdy, dependable heater!

This heater is so sturdy and handy for use in our fishtank! We love that we can set the temperature and basically forget about it since it is pretty indestructible and self-controlled. My fish seem to be happy with it and that makes me happy too! Product received for free in exchange for an honest review.

Highly recommend this heater!

I am an avid fish hobbyist and have gone through my fair share of heaters. This is a great heater for a tank up to 20 gallons. I love the sleep design, and the performance has been outstanding. No issues to report so far. I will repurchase this heater for any additional tanks I purchase. Would recommend. I received CashBack on this purchase and participated in a CashBack program.

Aqueon Heater

Heater works great as expected, I got one in and was broken on arrival, I sent an email to customer service and they responded right away and sent out another one the same day. It arrived in good condition and has given me great service so far, I highly recommend this aquarium heater
