Question 2, water flow and designs for reef tanks

[rickjames]

I also run two tunze streams in my 150, a 6100 and a 6080. Now that the corals are growing in I could see myself adding some more flow.

I also backed off my return pump from 750gph to probably only 400gph and I have noticed my skimmer has been taking out more gunk, since it ends up recirculating a lot of the water in the 75G sump.

Tunze streams are probably still the best way to go IMO.
