Do you think I have enough or the right water rotation?

The more the better for me.

Think of it this way, both AC110s have a 40ppi sponge in them so they will only filter large depris. They will not capture anything small unless you put a smaller PPI sponge in and then they will just overflow.

In a large W/D you could use very large stepped pollishing pads for your micron filtration and stick to one pump.

You can have all the filters and flow rates you want, they will only filter particals that will get trapped by the 40ppi and a possibly 80-100ppi sponge. Dust will not get captured AT ALL. You will need polishing pads for that and you can't use polishing pads in AC110s without them overflowing soon after. Ditch the 110s and think smart . Use one or two filters to achive better filtering quality than the AC110s could ever offer and have a lower turn over rate.

Worried, not really worried but I just want an almost zero dirt tank. By dirt, I meant dust and fish poop.

Not really trying to accomplish anything but a pristine looking tank. Besides, all my filters are gonna be transferred to my future 300 gallon tank plus an additional 120 gallon wet dry. That's another purpose there.

Since you have a bare bottom tank, why dont' you consider adding "poop" suckers?

In the 32 months our tank has been running, there has been no debris to vacuum up. Debris scuttles along the floor and is quickly removed from the tank. Strategically placed, poop suckers work very well. While we have separate, major mechanical filtration, you could easily make poop suckers by extending the uptakes on your HOB filters so that they are just off the floor. You can find pipe or hosing to make extended uptakes.

You are on the right track in terms of circulating the water. Our main mechanical uptake is on the far left. The mechanical return is on the far left with the nozzle angled to the left. Our current is so swift and powerful, that it bangs off the left wall and heads back to the right side of the tank. Our left overflow box is capped off, and we are using the right overflow box for the uptake to the wet/dry filter. We feed on the left side of the tank, and very quickly the uneaten food races across the tank to try to enter the right overflow box. So even though we have gigantic right to left current, we also have very swift left to right flow. Strategically placing your uptakes and returns can really help circulate the water. (A big pump helps too )

Between the red oscar and the pacu is the FX5 uptake (redundant filtration). Behind the pacu is one of the poop suckers. Just to the left of the right overflow box is the FX5 return. So our biggest return pipes are on the right. The return from the wet/dry is flowing into the capped off overflow box...so we aren't using that return flow for any tank circulation.

This shows how swift the flow from the mechanical return is:
