Starting on the plumbing. There will be 3 drains from the overflow. I am going to try a herbie style - full siphon gate valved line with the next being the trickle and 3rd is backup. Not quite a bean animal as I won't have the Ts, will see how it works, I don't mind a little noise but I can modify it as needed/desired. The drain I have going into a Y so it uses both filter socks. Waiting on the tank for the other drains. The return is 3/4 with 2 holes farther outside the overflow. So I have from the pump into spa flex, coupling, a T split - flex and clamp, - ridged to the other side under and outside the primary drain and clamped. I think it's pretty good so far. Black PVC, black fittings, coupling and gate valve painted black with fusion.
