Sorry Rodger should've been more clear.
Rodger that really needs to be increased IMO. That will probably lead to serious algea issues and detritus buildup on and around the rocks, the minimum is 10x turnover rate but that is the absolute minimum I would try to get at least 20x turnover rate.
Here's a quote from by J. Charles Delbeek B.Sc., B.Ed., M.Sc
Quote:
Water movement is extremely critical in a reef aquarium. Many of the
organisms you will be keeping such as corals, cannot move from where
they are growing. They depend on the water to bring them oxygen and
nutrients, to take away wastes such as carbon dioxide, to remove
fouling organisms and to ensure that all the polyps get enough light.
This water motion can be achieved in many ways but it should not flow
in a straight line (laminar flow). Best are small eddies and swirling
masses of water that cause the water to flow in a chaotic manner
through the aquarium. This is best achieved by having a number of water
returns and/or powerheads in the aquarium, located such that their
flows can interact with each other. Water motion is also critical for
the suspension, and removal of detritus and debris from the aquarium.
Make sure that you have good turbulence at the water surface too, as
this greatly aids in gas exchange.
