How to reach 50 - 100 GHP flow rate for UV?

[arthurTC]

Hi,
I am trying to use UV to control the ich in my tank and I realized the Protozoa Bacteria water flow is around 50 -100 GPH. Any suggestion on the pump I am using? I could get an alternative return pump (don't have a manifold) but for the DC pump, will the low speed setting on DC pump achieve that? or any other suggest to the pump?

Thanks!

You can test the flow rate by collecting the output water from the UV in a measured container. Use a stopwatch to measure the amount of time. Then use math to find out how many gallons per hour that is.

Set up a separate (right sized) flow loop in the sump?

That makes sense. My concern is: Can those DC Pumps operate at that low speed? is that an option for them?

any suggestions for a Red Sea tank? thank you
