JBL ProTemp S aquarium heaters incorporate the latest technology and are suitable for use in both freshwater and marine water aquariums. A protective plastic grid around the quartz glass prevents fish accidentally touching the hot surface and suffering burns.

This heater is much more accurate than my aquael heater. I looks like i'll have to upgrade the heater in my hospital tank to one of these as well. I also like the plastic burn protector.

Good heater with plastic covering to protect the heating element and from scalding live stock. Temp control doesn't seem as accurate as the eheim/jager heaters but a still it's a solid all round product.
