600 Gallon Upgrade Build

seriously...its no big deal;
- 5x tank turnover = about 2300 gph flowing through your sump.
- make sure your skimmer is rated for about an 800 gallon tank, then just buy a pump according to what the manufacturer recommends for that skimmer.

I know. I have that pump already. I just for kicks and grins would like a flow meter to just see what's coming out my returns.
 
Not really familiar with the vents near the end of the drain line design you have.
why not simply have vents on the top of your drains like in a conventional Durso setup? unless you faced air pockets without the vents in the end I don't really see a need for the vents down.
when things are solved I would rather have a tube extension to your drain so that the output of the drain sits 1-2 inches below water. That would minimize splashing sound as well.
As for recommended turnover rate I believe larger tanks could benefit from higher than 5 times turnover. the higher the in tank flow the more the need for higher turnover to efficiently suck all the floating particles. Also sometimes in tank pump positioning works against particles floating straight toward the overflow.so a higher turnover rate works best.
As for the skimmer argument it does have value to it but many times a skimmers input ends up sucking some of the already drained water, so a higher turnover might prove better for this as well.

Plumbing a tank is like setting up a suspension on a car, its such a dark art and hard to figure out the optimum setup. Not sure about your drain issue, im using two pumps at 2150 each and two at 1350 each pushing about 26" upward through 3/4" flex hose. My two drains are 1.5" and its flowing enough to feed more than 5000gal/hr. Its a little noisy but doing it. You have two inch that should do much more than 3500 and hour I would think.

I would think to but with the RC calculation it seems I am exceeding my limitation. And thus the reason I don't work on cars.

I tried a new plumbing idea and did the durso on top of the sump instead of placing it in the actual overflow. I was thinking that a higher flow rate will help remove more particles and get collected in the filter sock so the protein skimmer works more efficient? Thoughts?

How did the Durso on top work?
Agreed on higher flow rate removing more particles but I would rely on in tank pumps or closed loop ones to get the particles in the water column and a decent turnover to the sump to get those to the filtration.
You basically have total flow to the sump and 2x 2" tubes for drainage? I would think it should be no problem as I'm running around 4000G return pumps through 2x1.5 inches and 1x1 inch drains.
To increase flow capacity if you insist on increasing your flow further would suggest to close down one of the dursos completely to get a full syphon and add a valve to keep the level steady. the second drain can have a durso to slow it down or can just be used as an emergency drain. Still I always try to avoid limiting a drain as in case of blockage the remaining drains won't be able to handle the added flow.

My simplistic understanding of any type of venting of water pipes is that the air has to enter behind the water, not after the water is already in the pipe. That means the opening for the air has to be above the point where the water first enters the pipe. That's why a Durso is done up in the overflow. I don't know if that kind of thinking helps explain it any better to you.

Yes Dave it does. I made mistake trying to develop a new way to plumb.
 
If it was all a set science this hobby wouldn't be half as fun. Take it as a learning opportunity and enjoy the process.

Durso at the top is probably the best. You can quiet it down by running an airline tubing from the top cap all of the way down to your tank sump to help mask the sucking sound.
 
I have heard of the airline tubing trick before, but frankly, I have never had a Durso that made a sucking noise so have never bothered.

Some people are extraordinarily anal about tank noise. One person's sucking is another person's zen ;) I have no problems with the noise on my durso's either, but again, a lot of that comes down to personal preference.
