Canesfan44, to answer your earlier questions about how the skimmers perform without modification...
I can't attest to the 1000 personally, since I have the 3000. However, from the performance of the 3000, I would say the PCI skimmers perform well for the price point. I'm looking at upgrades to make me $400 skimmer perform similar to those priced at $1100. Even if I have to upgrade the pump to an OR3700 or Sedra 9000 (anyone care to comment on which one?) for an extra $100, I'm still ahead $500-$600.
I don't think you'll find a better exteranl skimmer for $188. The only thing close would be the ASM G1x ($202) with a recirculating mod ($20). Even then, it should be used in sump, since the ASM skimmer have a habbit of leaking at the cone. The PCI skimmers are really a lot better made, IMO.
