which Air pump?

[Aj_999]

I am currently modding an older skimmer and I am wondering which air pump I should use to go with the Rena 2" airstone as seen here: http://www.marinedepot.com/md_viewItem.asp?idproduct=AP7251

Does anyone have any idea? Any help would be appreciated.

Thanks,

AJ

Bump! Anyone? I was thinking of the optima air pump by Hagen.
