Tunze for a 72g

[beaker77]

Would one Tunze 6000 be enough flow in my 72g tank? I mainly have LPS but I'm going to start getting some SPS soon. Right not I have two Seio 620's in the tank and don't think it's enough flow.

seio 620s arent that much flow
1 6000 is about 40 times stonger than those

here is the deal i would start with a single 6000 and controller if not enoff flow than you can change the power (75.00) and make it a 6100
