Plumbing Help 180g

[Scooba]

I am finally at a point where I can get started working on my 180g again and I was hoping to get some input or critique on the plumbing I was intending on doing.

The tank is a 180g RR with dual overflows. I was going to do a herbie setup on them with two drains w/ gate valves for adjustments and 2 emergency drains dumping into the large middle refuge in the sump.

I am planning on doing a single line return up the back of the tank with black flex ball nozzles and a 2nd return in the future with a manifold so that I don't mess with the pressure on the main return and the herbie system.

Any issues with this setup that I may run into?

What return pump are you going to be running and what is your target turnover (or flow rate) for the return?

I was planning for about 8 to 10x turnover. Right now I have a DC-12000 which max is 3k gph I believe. I do plan on getting a newer pump though, which was why I was trying to determine plumbing design so I can get pipe lengths, elbows etc to get a rough idea on head height.

Your overall plumbing design looks pretty good.

IMO, valves in the return is a bad idea, especially when every drain has it (no emergency drain).

He's doing a Herbie style drain. The emergency drains are drawn and do not have valves. Looks good to me.

Yeah emergency drains are wide open. The only valves are on the returns to adjust the siphon

Ok. I didn't notice you had emergency drains.

2 Herbies are very difficult to balance. I would use 2 dursos.
