That was a good read on the refugium. It will be very easy to incorporate into my existing sump. I will definitely be trying that.
The wave maker is easily adjustable for flow amount and direction. I'll keep it on there then.
Thanks for the advice. I also ordered Diana Walstad's book today - looks like it would be a good source to have on hand.
Here is the standpipe I made for my overflow:
