Wide 90 Gallon build!

[purelife]

I am in the process of planning out the plumbing and could use some help on how best to lay it out.

Attachment 5174

That is a quick and dirty picture of what i am thinking on how to lay it out.
What i need help on is where to place the unions and where to place the ball valves. I am also thinking of splitting the drain line so i can divert some of the water to a 10 gallon mangrove tank but that's a plan not confirmed yet.

Help would be great thanks!
