"A Coup D'tat"
Just your luck.I wouldn't touch a Juwel heater with a 10 foot barge pole, I've been through 3 and they've all boiled my fish, all of them 100 watt heaters. Get yourself a Fluval E series when you can, because you won't regret it!
Give it a day or so and see if it heats up, using a thermometer.
You had bad luck this morning on CoD aswel
Anyway Are juwel 200w heaters good?
