Hi there my heater is built into my external filter however it is powered with a different plug. My socket trip switch keeps blowing when i plug the heater in and i believe this is due to a puddle of water i found around the base of my filter ( earlier water change ) anyway bit of emergency, will the heater element have shorted out? Have changed plug fuse to no avail. Just worried im going to lose my silver shark, the only fish in it at the moment.... 275l tank, eheim pro 2 filter. Please help with any info u can.
