The PMUP is a 24VDC submersible pump that was designed to directly connect to the DC24 accessory ports on either the 1Link module OR the same ports on the new Energy Bar 832. If you own the WAV powerheads or the new Apex, then you have a place to plug it in! These ports are switchable and can power the pump on and off just like any other outlet on an Energy Bar. The PMUP is a multi-purpose pump that can be used for many different tasks on your aquarium like:
Automatic Top-Off (ATO)
Carbon reactors
GFO reactors
Biopellet reactors
Many other salt or freshwater uses
