Sorry GAb, never saw that you posted here.
Plumbing is now done, just waiting for some electrical work to be completed then will be filling the tank up!
Here's the plumbing walk through:
Water enters weir
goes through external durso and down into sump
Goes through sump chambers to pump. From the pump it has 3 different places it can go.
Up - to re-enter the tank
Right - to reactor
Right then straight - back into refugium. This is to tune down the pump
Right: into the reactor and back out of the reactor
Up: Two different ways to go.
Up - into the wave maker which then splits into two separate directions.
Right - Extra outlet. This may never come into use, it is in case the wavemaker breaks, needs maintenance, or I just don't like the wavemaker.
Three outlets back into the tank
