PLUMBING TIP: Red Sea Reefer 250G2

Working on the plumbing for our new Red Sea Reefer 250 G2 and found a bit of the instructions that weren't too clear. I'm hoping this helps someone else! This is in regards to the pipes that go into the overflow box. You actually have to thread/screw each pipe into the bottom of the tank twice. ‎‎‪@Redseafish‬
