Tetra HT Submersible Aquarium Heater

This heater works fantastically.. I ordered it for my 3.7 gallon aquarium and it had no trouble heating the water up to 76° and maintaining that temperature even in winter when the indoor temperature in my house can drop to about 60° or lower. It has a long cord so you don't need to have your aquarium by the power source which could be dangerous. It secures to your tank by a suction cup which is very strong.. if secured correctly the heater will not come off. Good heater at a good price.. it works great can't complain.

Mini akvaryumuma uydu. Çok rahatım. Balığım üşüdü mü diye düşünmüyorum. 👍🏻

Excelente producto! Lo compré para usarlo en la tina de agua de mi tortuga que necesita estar entre 24° - 27° C y en épocas de frío baja mucho la temperatura. Mantiene la temperatura deseada calentando aprox. 60L de agua. Mi tortuga y yo estamos felices con la compra :)

Funcional y mantiene el agua de mi pecera a buena temperatura, practico, y fácil de usar

it works fine. it keeps my tank around 77-78. i only use for a week but seems ok. the betta fish i have dont seem to have any problem with it. the cable is long enough. i would recommend for a small tank 5 gallon max 10 gallon. i wish there was a button to control the temperature as i would want it slightly hotter but this temperature is ok.
