Return pump flow restriction.

Hello guys. So I'm planning the plumbing on my 120/150 (not decided yet) gallon tank and it will also have a frag tank in the same system. I was planning on using a mag drive 18 but since the frag tank will be 5-6 feet away horizontally and 4' vertically I'm worried the pump might be over powered for the tanks and I'd have to reduce the flow too much.

The mag 18 is rated for 1800 gph at 0' and I only want 100 gph going to the frag tank and 600 going to the display tank. It will also run miscellaneous reactor. I chose the 18 because I can use it for future larger builds as well as its price. Height from pump to display tank will be about 5' for the 120 or 5'6" for the 150.

Will lowering the flow too much have drastic or catastrophic issues to be concerned about?

This is kinda what I'm aiming for but spaced father apart ( fiancé didn't like how they look so close together)

 
Keep in mind, unless your going through a wall with the plumbing, the further apart they are, the more plumbing you will see between tanks. Why not just get an absurdly large tank with a moderately sized sump below with room enough to put a detached refugium next to the sump. If the stand had let's say 3 or 4 doors, the door in front of the refugium you could change to a glass door or tinted glass door so you could see the refugium all the time. If you didn't want to do something like that I would make a built in cabinet going from wall to wall with some nice bottom trim and crown molding top rail and then have both tanks farther apart and you would not see plumbing and cords.

The plumbing would be hidden behind the wall so thats not a big issue. As far as getting a larger tank, 150 tall is the largest tank I can afford at the moment while also planning a wedding. Ideally I'd want a 8 footer but the soon to be mrs. would kill me.

Besides heat build up would there be any other issue? When counting head pressure does horizontal flow act the same as verticle? Can a pump with 12 foot max head height only push water 12 feet up or 12 feet horizontal or can it push water sideways easier? That's my main concern. Thank you all for input
