Key words being if you design it right! I know on my 230g when I have tried to up the flow it is bubble city in my display (I didn't design this system). I have always heard for pods, micro and skimmer you want a somewhat slower flow through your fuge/sump. Am I all confused again?

your assuming that there is a fuge in the sump, personaly I don't think a sump is a place for a fuge as it is for equipment. a fuge should be a seperate tank that is filled by a pump and overflows back to the tank this way Pods are given the best chance for survival and you don't have to worry about how to fit it all togeather and optimal flows.

My refugium is in the sump

but with some baffels in the sump to slow down the flow and reduce bubbles i hope i will be okay. i am thinking on running a mag 18 i have a seio 1500 and a ehiem 2620 closed loop cannister filter i hope this is going to be enough but i can always add another power head. what do you think???
i just did the calculations and it is roughly 4300gph

I think that a lot of us have fuges as part of the sump as getting one that is properly set up as Steve says that overflows into your display can be challenging as far as getting it set up and not look either funny or butt ugly. My experience with canister filters has not been great - they tend to get clogged up and require a lot of maintenance and also seem to really lose their flow so don't know how much I would count on that as a closed loop but if you can keep it free from sludge build up you might be fine. Baffles are not going to slow you flow down but may work well to make the air bubbles pop before getting to your return pump.

I had trouble putting 50x flow through a sump with 3 baffles, couldn't get rid of micro bubble problems. So I guess the key is in the design.
