CPR AquaFuge Hang-On Refugium

[rtsen]

I'm thinking about adding a refugium to my setup to grow cheata algae for nutrient export but I'm still a newbie so I don’t want to worry about plumbing/extra pump/etc. I was thinking about modding a AC70 or AC110 to a mini HOB refugium but then I saw the CPR AquaFuge Hang-On Refugium on J&L:

Anyone on CR currently use the AquaFuge Hang on Refugium? thoughts? reviews?
