I set up my waterbox reef 130.4 two month ago. I was using a breeder box as refugium and it was working until the chaeto grow from a tennis ball to a football, so today I just bought egg crate to create a baffle to keep all chaeto and skimmer apart and some PVC pipe glued on another piece of egg crate to build a simple frag rack. Total cost is less than $20, hope this will be working.
