Vortech arrangement

Hello.

Have about 15-20 acro frags in my tank right now. I have about 120 pounds of live rock, 3 columns or pillars, left, middle and right. About a foot so in between rock piles. The tallest column on the middle goes above it 2/3 way up the tank.

Currently have 2 mp40s, one on each end. They are staggered off center a big, about 2/3 to the top the tank.

I have an mp60 coming either tomorrow or Tuesday.

Do I put the 60, on day the left side, leave a 40 on the right, and the other 40 back wall? Or two 1 60 on one side, and the 2 40’s on the opposing side, so I’ll have two on one end?

Or just use the 60, 1 40 on the other side, and keep the second 40 as a spare?

Also, right now they are in anti synchronized mode,via the reeflink, do to different flows. For example, at night is lagoon at 45 percent, early in day reef crest at 50, middle of day reef crest at 80, and then before lights go out nutrient transport mode at 70 percent.
Should I run the 60 the same way or just leave it in constant mode ?

I hate to say it there is no easy answer, took me 8 months to place my 4 MP40’s around the tank and they are all staggered around the tank at different heights running a rotation of reef crest and constant mode 60-80%. This was the only way all the coral took multi- directional flow. Part of the pain in the butt for me is I have a mixed reef. In hindsight I would’ve just went sps dominant. For each pump on the end I run one constant and the other reef crest, the two on the back wall just alternate every hour with different percentages and programs.
