DIY Skimmer design questions....

[jgoldsney]

Ok all you DIY skimmer fanatics....have some questions fo you .....

I have this model protein skimer....
http://www.wonbrothers.com/product/skimmer/clean200.htm

I don't know if I got a bum one or not...(the ones at aquagiant seem to be working fine) I haven't had much luck getting it to work consistantly.

I would like to convert it to a recirculating skimmer design and feed it from my return pump which is a little powerfull.....

What size pump should I use for the recirculation? I have a couple of 700 gph pumps....would this be too much..

Any ideas on design mods to this skimmer would be awesome as I am just in the design phase of this.
