See what I got in mind is full PVC piping support that I can hook up a pump to. Then drill holes at the top around my sps , it be kinds like steam vents in the ocean but not Steam. It's going to be a full piece for my new 75 gallon tank I got from concepts . Tank is 44" x 24" x 20
Using rock rumble to cover as much as I can ,then glue shells and sand and crush coral to cover more of the PVC . I plan on using black sand with whiter rock then I got now. I got 45 pounds of live rock for my sump so I might mix a few nice pieces in to . It's going to be interesting .
