fishcam January 19, 2009 January 19, 2009 If you've got a Hydor Koralia controllable pump, could you please snap a pic of the label on the power head, and possibly the end of the connector? I'm trying to figure out if these can be driven by PWM or a variable voltage... so I don't have to buy the expensive controller! Thanks!
