Sump size for reef tank

[Kyle Pitts]

I have a 65 g reef and have a wet/ dry sump at the moment and would like to build a refugium out of a small tank. My question is will a 10 g tank be ok for the 65 g reef? I don't have to much room so I don't think I could go any bigger. Or should I just stay with a wet dry

That would just be big enough to hold minor things, unless you just plan on using it for macro algae, won't be a lot of room I'm thinkin for a skimmer to match your size tank.
