Deltec, Euroreef and H&S all make good recirculating skimmers. Maybe you should bite the bullet and get your tank drilled and get a sump??? I started with an undrilled tank and HOB skimmer and I really regret it. Already looking to upgrade!!! You need to try doing things right the first time in this hobby (and not necessarily cheaply), or you'll regret it and pay DOUBLE!
