Overview

JBL ProTemp e300 is a comfortable external heater for aquariums from 90-300 l capacity. The JBL ProTemp e300 makes a conventional heating element in the aquarium unnecessary. Many aquarium keepers are bothered by technology in the tank. A heating element is often very large and takes up a lot of space in the aquarium. The JBL ProTemp e300 is ideal in this case, as this heater is installed outside the aquarium (e.g. in a cabinet). By installing it in the water circuit, the heat distribution is much better than with conventional glass heaters, where the area around the heater is always slightly warmer. An external filter or a separate pump is required for operation. The operation of the heater is very simple. The desired temperature is set with just one button. The current water temperature can be read at a glance on the LED display.

    Excelent product and build quality. Very accurate in function. 25C, not a single variation. I would recomand it without hesitation.
