Just so we are all clear here do you plan to only be using the Mag & your returns for you tanks flow, or will you have other water movement w/i the display tank itself? I think that Mag24 pump is like 2400gph or something like that am I close?
The skimmer I have runs at about 750 gph, so I think the mag18 (901gph after all the plumbing) would be a good match. The next step down would run at 660gph, so that would be under. If i've learned anything in aquatics, it to go higher rather than lower.
I moved your thread over to Member's Reefs since it's more of a reef build than an individual DIY project. If you get to the point where you have a photo, you can edit your first post and attach it to the post. Keeping this updated with the latest will then display on the forum display page.
