Just wondering what you have found that works for your 90. I have mine set up for about 6 weeks now and have a pretty strong flow out of my return line AND a Tunze 6085, which I think is too strong. I think this because my first 2 fish, small perculas, are pretty much swimming with their bellies pressed against the back glass. When I turn off the Tunze, the are swimming around the tank like a normal fish.

I am looking into trying to sell this one and replace it with something but not sure what works best for a 90 and I am hopeful to hear what you guys might have that works. I am open to everything.

I've got 2 evolution 1400's and 2 evolution 750's in mine. Which still gives me 47 times turnover. Plus with the Hydor wave maker I have the front left and back right on one cycle and front right and back left on the other cycle.

If you have the budget (which I don't) the Tunze Wavebox and a couple of 1400's would be a great way to get good flow.

I have the return pump going ~400 gph, a koralia that is around 500 (can't remember exactly which one it is), and 2 JBJ 1600s that alternate so I get varied directions of flow... So about 2500 total GPH or 27x turnover. Not a ton, but is plenty for my needs at the moment.

It depends on the corals too. LPS don't like to be whipped around like SPS do so having ridiculous amounts of flow in your tank may not help any of the livestock. I have two MP10s in my 90g, which with the return, is more than enough.
