I use this in my tall 40 gallon tank. It¡¯s worked out really good and I saw an immediate change on how my fish behaved. It does a great job, very stable.
The heater has a rapid heat setting, very pleased with that! There are 2 suction cups included and an extra one. Its easy to put the heater on the tank. You can mount the controller on your wall if you wanted to. The power cord is really long so no worries of the cord being to short. To me, this seems pretty good quality in comparison to other heaters Ive had in the past. Overall, very pleased with this purchase.
This tank heater works great and it’s easy to use, with a wide range of heat levels to suit every tank type. It’s very solid and durable and keeps my tank at the exact temperature it needs to be at. My favorite quality though is the peace of mind that I’m not going to start a fire or burn my fish because I forget to unplug it before doing water changes. The auto-off feature when it is out of the water work instantly and reliably every single time. I’m loving it!
