Flow rate !
 

Hey, I have a new 60G tank and I have 2 Koralia #4 Is this to much ?I wana have a mixed reef and some fish. But the aquascaping is really open and was wondering if the fish will have a hard time with the flow ?
Thanks

Shouldn't be too much for the fish. I'd be more concerned about getting the flow right, with respect to the corals.

I'd say, if anything, it wouldn't be enough. Depending on coral species, of course.

Should not be too much flow, especially with some sps ( may require more flow). With those powerheads you can also direct them to rebound off of the glass or use the attachment to make the flow more direct and strong.
