With regard to the mag drives they do specify 1.5" ID to obtain 950 gph(mag 9.5) at 0-1' head. They actually have this info in their instructions. they don't take into account elbows and other restrictions but that at least is a baseline. These pump are intended for vertical applications.

That I don't know. What I do know is I got about 75% more flow on my mag 7 when I switched from .5" to 1" plumbing. "Proof is in the pudding"

This is turning more complicated than it needs to be. Carey- you have two things working against you with return flow- the check valve and head loss on both returns. If you want to use both returns you will need a bigger pump to get more flow. If you want more flow and still use the 18 you need to send it up in 1 tube, not 2.

Id never run 1.5" ID, unless its to a split. I dont care if the mags specify it or not. The output is 3/4" on the pump and the bulkheads for the return side are 3/4".... putting 1.5 on the pump isnt going to do a single bit of good unless you were to increase the diameter on the bulkhead. Id eliminate any 90's, replace the spring valve and run the mag 18. Thats it

Exactly. Which is why I suggested 1.5 from pump to T split. This will give the maximum flow to both returns.

For now, I am going to leave it as is and use powerheads for additional flow. I am leaning towards running dual return pumps and if that isnt enough then instead of two locline outputs i will go with one on each side. I am kinda broke right now so I dont have the funds to get new plumbing pieces like the clear check valve and the slanted t connector. If it becomes an issue then I will find a charge card with enough room to buy them.

So, today I mounted 2 powerstrips on the right side wall inside the cabinet, it is 3 feet away from the sump so I hopefully wont have water issues with it. I also started playing with the rock lol, this is one of my fun things to do, I love creating rockscapes.
Also, I have 3 powerheads going right now, two on the right and one on the left. They are all koralias, just not sure which ones as the tags fell off and I have so **** many of them! lol There is good flow though and decent surface agitation, there are prob 2 1400's and maybe a 750 in there tight now. I think I will be getting another wp40 next month when I get paid so that should take care of flow.
Here are the first pictures of the rockwork, I know, I have a long way to go, lol, but the left side I am pretty happy with. I also put a compact dual 96watt 4 foot light fixture over it for now.
