- Check heater for any signs of damage before use.
- Attach suction cups to the heater at the upper half of glass heating unit.
- Mount heater vertically inside aquarium using suction cups. Choose a location with a good water flow. Make sure that the water line is not lower than the bottom of the temperature setting display as this will expose the heating element to air and can cause the heater to fail.
- Wait at least 15 minutes before plugging in your heater. This allows the heating unit to adjust to the current temperature of the aquarium water.
- Create a drip loop. Then plug the heater into an electrical outlet.
- To set heater temperature, use the temperature control knob located on top on the glass heater. Most tropical fish prefer temperatures around 76-82 degrees Fahrenheit.
- When the light is on, this indicates that heater is on and heating the water.
- When light is off, the temperature (heater) has reached the desired degrees (temperature) setting.

don’t recommend for long term
By Cristian on Jun 21, 2021
I’ve had this for around 2-3 months and it finally broke, I used it for my goldfish tank to keep a stable temp, and then it started going above the temp or it wouldn’t move at all overall I rate this a 2.5/5 because of the looks.

Great Heater
By Joeii on Apr 22, 2021
I received this next day. Thank you Chewy. I like it. Most heaters are preset these days. This will go up to 100. I keep it at 82 to kill ick! I've only had it a day but it's a sleek design, glass feels fancy. And the best thing is it came with TWO suction cups.

Thank you Chewy customer service!
By linz1745 on Feb 11, 2021
As pictured, my first heater I received the glass tubing within the heater that surrounds the coils had shattered, I believe it was accidentally dropped or unintentionally mishandled in transit. I called Chewy customer service and let them know and requested perhaps the replacement be marked fragile. They shipped me a new one and it arrived NEXT DAY! The packaging was extra padded and I did find the box was slightly opened but that just showed me there was care in ensuring the new one was not damaged before shipping. THANKS AGAIN for your excellent customer support! As far as the heater goes I look forward to getting this set up. Very nice heater I just wish the glass tubing on the inside was As pictured, my first heater I received the glass tubing within the heater that surrounds the coils had shattered, I believe it was accidentally dropped or unintentionally mishandled in transit.

My recommendation is to call Chewy to order to make sure there’s some extra padding before shipment :) … more

Bought in March, broke in April
By Alexis on Apr 25, 2021
I literally just bought this heater and it has already broke. Highly disappointed, not sure if this is a fluke or what. I would like to have this replaced or a refund. Ridiculous.

Works Great!
By CAROL on Apr 9, 2021
The heater in my 75 gal stopped working. I went on line; did my research, and this heater met my needs the best. I ordered 2, and received them in 2 days, easy to install, so far working fine.

Great Heaters!!
By Laurie on Feb 5, 2021
World Of Fish in Minneapolis MN used to sell and recommend Ebo Jagger heaters but they quit making them. Now they recommend and sell Aquatop Heaters so I bought one in October and working well. You can easily set the temperature like you could on the good old Ebo Jaggers and that is a great feature if you want quality and don’t want to spend days upon days getting your temperature right. I have the 150 Watt in my 30 gallon aquarium.

Acceptable but not perfect
By FishyD on Mar 19, 2021
Don't expect the temperature you dial up on the heater to be what it actually maintains the tank at. Mine is about four degrees off. Other than that, yes: it does it's job. Just monitor the temp with an actual thermometer.

Good heater for the money
By Rick on Mar 6, 2021 top1000Contributor
Aquatop heaters are not my favorite but they are reliable and don't cost near as much as some heaters. I don't care for the little temperature adjustment stem because it is hard to hold firmly while turning and very hard to turn.
