Why not just enlarge the area where the main inlets come in and have that be the refugium? I doubt the extra flow would bother any fry too much.

It seems you don't really have a lot of actual filtration for such a large sump. The wet / dry definitely makes a difference in effectiveness because the bio media is exposed to so much air exchange, but it does make it trickier to minimize CO2 gas off. Everything is a trade off.

Having filter socks isn't a bad idea actually. Nothing is set and forget, but if you use the socks you pretty much never have to clean the biomedia, which is a nice trade off. The foam pads will protect it some, but not nearly as much as filter socks.

I'm using only poret foam in my wet dry right now. The pre filter in the overflow box is 0 ppi, then 4" of 20 ppi and 2" of 30 ppi. I tried to "set and forget" it for 6 months (cleaning the prefilter of course) and when I finally did clean it the 30 ppi foam was absolutely caked with mulm. It took a half hour with the garden hose to get it to run clear.

I guess I'm confused at your filter sock logic, change something out every week, or change something out every several weeks/months if I don't use filter socks?

After thinking it over, I may just go full wet/dry setup with no refugium. Refugium's are cool, but at the same time, I feel like I'll have plenty enough to worry about with the 60 gallons on top that I won't really have a want for one. If I do, I can always setup a smaller tank and close loop it into the system later.

So if I'm going full wet/dry setup, what is the best way to utilize a wet/dry setup with a bean animal overflow to minimalize co2 loss?

The sock filters are much easier to change out so I figure the actual amount of work is about the same, but just spread out more often.

For a full wet / dry just make a top to cover the wet / dry portion of the filter. You'd still need a small area that would overflow onto the trickle plate since the bean animal style overflow doesn't prefilter. Otherwise, you'd be changing the pad on the trickle plate every few days.
