I plan on adding a 29 or 40 gallon glass tank for use as a refugium-- I plan on a DSB, with a live rock rubble pile at one end and will grow chaeto in it....
How much exchange of tank water do I need with my fuge??
I understand the flow requirements of the fuge and can supplement this with a pump/spraybar or powerheads in it (to get the chaeto tumbling) but wonder how much flow do I need to exchange with the main sump and tank-- will a low flow/exchange suffice (100 GPH or so or even less)-- or is this too low....
Secondary to this--- if low flow is ok....
1. Should I run 100% of my flow from my tank through my skimmer (this is a recirculating skimmer all the flow would in the top of the skimmer-- it does not draw water from the sump) and then tee off the return to feed the fuge (this would lower my sump/tank exchange to less then my 1x my tank volume per hour)
or
2. Tee off the water coming from my tank to the sump and run the water that doesn't go to my skimmer to my fuge??? Using my current pump would give me 200 GPH exchange between my tank and sump-- with about 1/2 going each to my skimmer and fuge.....
I know either way I'd be running either a low flow or very low flow sump/fuge-- just curious what the opinions on a setup like this would be.....
If you think neither give me adequate tank exchange what amount exchange with the tank would you recommend through the fuge?? I can size the pump I need based on this recommendation....I've been considering replacing my Rio anyway based on some horror stories of them frying and nuking tanks....
I would appreciate any comments...
thanks....

Anthony,
I was wondering the same thing as "Spuds". Is it best to pull water from the tank (raw water) to feed to the refugium or can it come from the "skimmed" water in the return section?
