SEOs or Closed Loop On New Tank

[jgoldsney]

In a bit of a conundrum on the plumbing of my new tank.

I have a Mag1800 as a return pump

For additional flow I have some options.

In my 230 that Is going to be coming down I have 2 SEO 820's and 1 SEO 1500
I also have a Mag1800 Return Pump.

I am Trying to decide what to do for Flow in the new tank.

I was going to try to have 1 SEO820 and the SEO1500 and the return for flow but am considering using my spare Mag1800 as a closed loop pump and only having the SEO1500 (it is still in the housing so it is not too hard to hide)

What should I do?
