DIY sump/wet dry filter

I'm not sure what to call it, I've never seen a wet/dry in person and I have no experience with sumps. But I picked up a 90 gallon with glass tops, built in overflow and a stand with a 30 gallon tank underneath for $180.

I am really on a shoestring to complete the setup so I was thinking a sump like vaultboy's ( with a few changes.

I have bucket with a gasket in the lid. I'm planning on drilling a hole in the lid for the bulkhead from the overflow. Inside the bucket will be about 4 gallons of lava rock with a hunk of foam on top. The water will rain down through the bucket and flow out the bottom side where I will make a bunch of slots.

The bucket is water tight so I figure the co2 will stay in the bucket like a sealed wet/dry. The rest of the sump will be for plant farming and the return pump. The return pump is a eneim universal 1260. It pumps 635gph.

Questions I have:

1)In bucket sponge on top, lava rock on bottom?

2)Bucket is 5 gallons. Ratio of rock to sponge? (I can also put sponge in the overflow and go all rock or rock or something else in the bucket)

3)Will I have enough flow? I'm thinking the turnover will be about 4-6 times per hour with head.

4)Can I run my co2 line right into the bucket and use it as a reactor, run it into the return pump or add a needle wheel (not preferred, $$$)

Thanks for your input guys!
