Bulkhead Flow ?

[brewercm]

Anyone know what sort of flow I can expect through a 3/4 inch bulkhead. This will be a gravity feed bulkhead from fuge back to sump.

That's exactly how I have my fuge to sump flow, through a 3/4" bulkhead. I have about a 10 gallon refugium, maybe I'm pumping 200 gph through it. I can't imagine you'd have a problem with this unless you wanted to push something like 600-700 gph through the fuge into the sump.

thats what I have running also, except my fuge is a 20 tall. The drain from the main tank maintains a little more than a trickle, anything more and it starts to fill over the drain hole. Then again, i could probably elevate my fuge more and get better flow, but they are lever currently with the hole drilled toward the top of the 20

Thanks. That's kind of what I was wondering. It's gonna be setting next to my main tank and was just wondering what pump to use without pumping more in than the flow will allow.
