Vertex 7" x 12" filter socks

[Baker]

Has anyone seen these around? J&l is back ordered and same with Concept. I don't think Wais or Reef Wonderland stocks them so just wondering if anyone's seen any in their lfs tours?

Gold had some 7" socks about two weeks ago.

post caught my attention as starting to look for large 10micron socks so after reading did a search for JL filter sock. Interesting one that came up is a company in Alberta that makes filters (JL Filtration), wonder if what they have, suitable for aquariums?
