One man's ( or tank's) perfect is an other man's (or tank's) disaster. There is no common 'perfect'.
Agree complete. Just set them so that you have random movement that is strong, but not so strong that your fish cannot swim in all parts of the tank or that the sand moves around.
Fish hanging out in just a few parts of the tank is a sign that your flow is too much.

Flow is important. But how do you measure flow? Your tank is a different size than mine, it has a different rockscape than mine, it has different corals than mine and different pumps than mine, so how do we compare?
About the only reasonable way to compare is overall turnover rate, and even that is a fairly course number. Low flow for zoas and softies, medium for lps and high for sps. But what numbers make up low, medium and high? And what about a very mixed reef. And will zoas and softies be OK with high flow?
IMHO, having good RANDOM flow throughout the tank is good. I know moew pumps make a tank look bad, but if you want really random flow, maybe a few smaller pumps is better than one big one. Wavemakers have been a huge step forward from the days when all we had were static flow from powerheads.
As jda said, as long as you aren't moving the sand around, and soft corals can stand upright, you're probably OK.

Op, what size tank do you have?
Where would you like to position the pumps you have? Esthetically, what look do you prefer? On the sides, on the back?
What livestock and corals are you running?
As you can see above, there are many variables to consider.
Once you get those set then you can proceed to setting up your flow. You might need to adjust pump position a little to keep from blasting some items.
It would help if you put together a build thread and set up the badge so we can see what you have when you ask questions.
I personally prefer a gyre flow. I have pumps set in front left and rear right. I set one pump to sync off the other. Since I have four pumps I set the other two in the opposite corners and have them on anti-sync. Then I set a flow timer to 5 minutes. So every 5 minutes the flow in my tank reverses In a gyre pattern.

i try to have a 360 flow on the system, i strongly agreed with you, flow is important, that's why i am trying to set it correctly on my 130 gal RedSea Reefer 525XL, i don't know how to measure flow, not sure how to compare as well, turnover rate
i try hiding flow from zoas so they won't get to much flow the rock blacks the flow
so i got RANDOM flow, my sps is dieing, they got bleached
SPS dieing and bleaching
There are a lot of people in this thread trying to help you, attaching a picture without any supporting information doesn’t help us help you. Someone asked about flow, so you shared a picture of an mp60. ok... and? What mode is it running? What % of flow? How many modes do you cycle through...

I do apologize getting back to you this late i have 130 gal RedSea Reefer 525 XL
my pumps are one on top left corner the another open is right bottom corner on the other side of the glass so i can get a 360 flow
i'll take some pictures also good idea, i have the gyre running 1hr only a day i'll adjust the input
i am having bad luck with the rocks, i have brown hair algae on the bottom site of the rocks not on the top. i was looking at my skimmer the other site where the light reflects i see the brown hair algae also on it, i'll take some pictures
