Well since no one answered my question I had to find it myself.
So for anyone I can help, here's the answer... How much flow should I run thru my refugium? The flow rate that will optimize your refugium will greatly depend on how you have your refuge set up. If you're using it for nutrient export then shoot for a turnover rate of five times your tank volume per hour. If you're using your refuge as a pod farm then you can increase this flow rate to ten times your tank capacity if you want. If you're using the refuge as a plankton farm then you will probably want a flow rate much lower than even five times the turnover rate. In summary, remember that you're not limited to what you can do with your refugum and that you can even install multiple refugiums on the same system. The size of the refuge should be as large as you have capacity for and while the flow rate does not have to be equal to the flow rate within your tank, it also does not have to be so low that it could be classified as a stagnant body of water. Please post any questions you have about this article or refugiums in general to our forums. References: -Natural Marine Aquarium Volume 1 Reef Invertebrates by Robert Fenner and Anthony Calfo |

Thanks for the information as I am setting up a 80 gal refugium for 290 gal reef. I am looking to get a little of each of the reasons you stated, in a separate refugium, but I do not want to run a very high flow rate as the refugium will drain into my main tank. The main tank already has 2000 gph from sump return pumps as well as Tunze powerheads for added circulation in the tank.
My thought was to have a low flow rate of about 550 gph. This equates to about 7 times the refugium volume but only 2 times the main tank vol. If you meant five times the refugium tank volume than I should be OK? Thanks Frank |

Thanks benray. I'm running about 200GPH through my 29G and it seems to work well.

Alan, thanks for the info it seems you have the same flow rate I am planning. Can you tell me how much sand, rock, etc is in the refugium.
By the way, the next time ask that Stewardess for her name and number. Regards Frank |
