once it sealed up with coralline about 3 more months after this pic. then a coat hanger was used to scrape out a viewing window for an extremely dramatic look. The vase was purple when you saw it from away, but when you approached it and looked into the round cut out all you could see was a globe reef waving on the other side. I was going to leave it like this is a signature mark of good ion support, but it obscured too many of the expensive frags from view so I slowly carved it all back out over time and gave away many baggies of coralline as seed starters. See, the little vase helped your big reefs lol
