The heater has been running smoothly for over six months. My 55-gallon tank stays at a consistent temperature even during colder nights. The glass is sturdy and the temperature control is very reliable.
Alison Mackay –
I installed it in my medium-sized tank and noticed a steady temperature. It doesn’t overheat and works well with my fish species. A little noisy at startup, but otherwise solid.
Lisa Poole –
Great value for the performance. The 200W output is sufficient for my 40-gallon tank. It’s easy to install and the glass construction feels secure and safe.
