I have a Reef Octopus NWB-110 that currently uses the Octopus OTP-100 pump. I bought the unit is 2012 and am looking to replace the pump. As I understand it, the Aquatrance 1000s. Is this correct? Do I need anything else to make the change over? When I look at the "Adapter Fittings" drop down menu, there's nothing for this particular unit so I assume all I need is the Aquatrance 1000s and I'll be good to go. Anything I'm missing?
