I'm assuming you would go with the large one? The problem with refuges is that you typically need a big refuge to make a dent on a large tank. If you do go with it, I'd recommend going with caulpera since it tends to export more nutrients than most other macroalgae. Just look up the potential issues with caulpera.
Finnex also makes a HOB refuge if you don't want to have it in your tank.
