"Tunze" of flow?

[Large Polyp Dave]

AGA 180 RR tank running Velocity T4 (1000 GPH) on returns for overflow

I obviously need more current so I'm thinking of running 2 Tunze 6100s with a Multicontroller

Would this be sufficient flow?

Yes, it would be great flow for SPS. If you are keeping lower flow animals you might be better off with the 6000's
