Several questions as my new overflow box is loud.

Should primary drain have tiny air hole in the top or not? Mine does not sure if that correct.

Should secondary drain have a lot of water going in in? If I adjust primary for less flow it seems more goes down secondary.

Thanks

primary no hole. it should handle most of the flow.

secondary should have hole if it has the downturned u connector. otherwise a straight pipe should work too. it handles the rest of the flow. just make it a trickle.

3rd is emergency, should be straight higher than all others and have no water in it normally.

Thanks, so my primary has a hole. It came that way so I will need to reconfigure that one.

If I want my primary to have a higher flow, how do I do that without making everything loud?

Thanks

Primary should have no hole, secondary does not need one. To change the flow in the main drain adjust the ball valve which should only be on the primary drain.

Primary with hole is no problem as long as entire u is under water. The small hole will help with priming/restart.
Primary should be lowest pipe. Secondary about an inch or so higher. Emergency an inch or so above all.
What size pipe? What size return pump? What overflow box?

What size tank?

400 gal

On a 400 gal tank you should shot for 3-4 x display volume max. Guessing with that pump you’re pushing too much water, causing too much to go down secondary, hence the noise.

Right now each return is showing about 400 gallons into the tank.

Also on the pump I miss typed. It the a200 not the 400

How do you like that A200? I have one, but haven't fired it up yet (still plumbing).

It awesome so far only started it a week ago and trying to get everything sorted out. Very quiet.

The noise is likely coming from one of these 2, maybe both.
Either water from inside box is falling too far into outside box. Making plumbing in outside box should fix that.
Or
Too much water is going down secondary. Opening valve on primary should fix that.

the easiest setup is to have no pipe on primary and put a strainer on it just in case fish or snail decide to go into overflow.

secondary is straight pipe as high as what water height you want in the overflow box.

emergency should be just a bit higher than your secondary, also a straight pipe.

put a gate valve on the primary, then you can adjust until water barely trickles down secondary. you can crank up the return pump and open the gate valve.
