yeah I just want a refugium. I'm already using a toms aquatics rapids pro series wet/dry with the bio media replaced with LR rubble http://www.tomaquarium.com/resources/userguides/proseries/filter/proseries-filter-english.pdf
That overflow is working well, just looking for a cheap low flow for a 10gal...I'm wanting to raise live pods and chaeto, my flow rate should be low for that right? The pro series filter has a built in skimmer, do you think I'd need another skimmer baffled off in the refuge? If I were to do that I should go with a 20gal, I'm assuming.
