to tell the truth when i had no sump i used the hydo efhi 300w intine heaters
i run them for 5 years with no problems
you just cut the return pipe of your exturnal heart put the heater in job done this wont work on a crappy fx5 as they have the crappy pond ribbed hose
the inline heater are great as they move the warm water around your tank better than having all the warm water trapped in a pvc pipe
