I forgot to mention why I have the return line going into my refugium.
I have 2 20 gallon tanks connected with one of them being the refugium. Both of my drains go into the sump proper where the skimmer and return pumps are. The refugium is a separate tank altogether so the return line goes into it which provides flow and allows the water to drain through the bulk head that connects the two tanks. This allows for a nice mild flow in the refugium and just like with the reactor it allows me to do this without an extra pump or electrical outlet. This reduces costs and equipment, electricity, and head into the water.
There's a thread somewhere on here where we discussed this. I was going to have a T off my drain into the refugium but someone suggested a pump instead so I didn't have to redo my plumbing totally. I realized that I could just use my return bib and it works great.
