MORE PROGRESS!!! I was able to get the plumbing roughed in today, and am pretty happy with how it turned out. I still need the check valve on my return to prevent back siphon if I lose power at all.
The drain is pretty straight forward. The return line has a "manifold" on it for future items such as a calcium reactor. I plan to use one of the valves for easy and quick water changes.
Let me know what you think! Again, this is still a rough in so I can change things.
