I was either going to get a bigger sump and add a refugium section or plumb in a separate refugium.
I currently run zeolites, FM additives and have phosphates of ~0.00 and nitrates of <5 but am interested in a natural alternative.
How big should my refugium be and what type of macroalgae should I consider?
Your input would be very much appreciated.

I would not add a refugium to your sump.
If you plumb a pipe between the sump pump and the tank and have the refugium sit higher than your tank here is what you can do. You place a valve between the pipe and refugium and restrict the flow to very slow. The inlet pipe simple hangs into your refugium and the out pipe comes from the top of your refugium and into the display tank. It is a gravity flow.
That way in addition to chaeto you can cultivate tonnes of pods and other things in the refugium to feed your large tank. The pipe from the refugium should go right down to the bottom of the display tank. If you do not do this, fish simply hang around the pipe and feed as the critters flow into the display tank.
I feed my refugium daily with phyto to encourage a highly populated refugium.
