I have a Bubble Magus 9+ skimmer - the controller is shot and I've tried contacting BM about ordering a replacement but have gotten no reply. My question is this - are all DC skimmer controllers the same? I have Reef Octopus DC return pumps and the controller is very similar - a DC adapter port and a three pin connector plug with a screw ring. Can I use *any* DC skimmer controller on my BM? Thx for reading.
