The heater works perfectly for my 10-gallon tank. The day and night temperature shift is subtle but noticeable, and my fish seem more active and calm. It maintains temperature well even on colder days.

I’ve used this heater for two months now and it’s very reliable. The temperature stays steady, and the day-night cycle helps my shrimp feel more natural. Easy to install and doesn’t get hot to the touch.
