@mrcole76 Thanks for the suggestion... that looks pretty cool, I might give it a try.

@BoSalman It really depends on your plumbing. You'll want to calculate the head loss and then compare the head loss to the charts on ecotech's website.
I've also got 1 inch returns and 1.5 inch drains, but I'm also going to be running Triton, so I'm looking to do 10X turnover.
It's possible the S1 might be on the weak side for your setup, and you'd be better off with the M1, but it depends heavily on your plumbing. If you've got similar piping in terms of length of run, elbows, etc to what I have, then you're probably looking at about 10ft head loss with an S1. The S1 running at 100% and 10ft head loss looks like it might give you around 200gph.
If on the other hand you've got a lot less plumbing and like only 5 ft of pipe, few elbows, then maybe you're more like 6-7 ft head loss. That would allow the S1 to push closer to 500 GPH. Obviously the M1 gives you more wiggle room if your head loss is higher than anticipated.
Even if your not doing triton, I usually aim for at least 4X turnover.
I use the following site to calculate the head loss (the flow rate is in GPM, not GPH, so divide by 60)

and here are the charts for the flow for the Vectras (scroll down)

Yes that's exactly what i'm doing. Currently running a 5000lpd pump, that's roughly 1320gpd divided by 20 power ranges give me around ~66gpd on each power range. I currently run it on setting no. 8 which is roughly 528gpd with zero losses.
My target is around 500-600gpd (4-5x) for the sump. This is why i was between the S1 and M1. Considering that i do run a manifold i was leaning towards the M1 more tbh just to have more room for any future plans.
My plumbing is around 9.5-10.5 ft (~3 meters) with only two 45 elbows and 3 valves and one T, so head loss is not significant? So i just take around 75-80% of the rate of the pump to calculate the required pressure/setting on the controller...
So i guess you're right on the M1 being closer to what my setup requires.
Here’s a quick scape I did this morning. Not sure if I’m 100% satisfied, so I may do some more playing around.
I think it looks cool. It has character - not just a pile of rocks.
Nothing but good things to say about my NYOS Quantum 160. Turned it on 4 hours after adding the live rock and bacteria per instructions and it’s already skimming great.
Here it was earlier being assembled. Love the build quality on it, and it’s also very quiet.
