Its been 6 months since my last post on my original thread! Well I never sold my chalice collection. Just couldn't do it. I do have some good news though. We just finished plumbing the second coral raceway (yea it took 2 years lol) but this plumbing design is going to be far superior to the original plumbing concept. I'm still at improving the raceway design for coral propagation. I will show off the new plumbing job very soon
