Mike brings up an excellent point: often the best setting for the pump will depend on your setup.
He also makes the best recommendation for a starting point: one on each side, high in the aquarium (perhaps 6" down), Reefcrest Mode. I would put the slave pump on anti-sync to get the most variety for that setup.
After you try this setup, I would recommend experimenting with pulse mode as well, again with the slave pump on anti-sync.
