I'm setting up a recently received 350 G2 Max. I'm replacing the metric hard plumbing for 1". I plan to connect the Reef Run 5500 utilizing flexible line. The issue I'm having is with the supplied adapter for the pump. It states it is 5/8" / 1". If I utilize this adapter and 1" flexible line I'm still restricted to the 5/8" opening.
Am I supposed to cut off the 5/8" end of the adapter? The manual isn't helpful.
