Say NO to Tupperware® in your tank!
Filter socks are so last year… these filter cups are all the rage! The Octo Cup™ is designed to work in with most popular sump configurations and is made of clear, 1/8″ acrylic. The outside flange diameter is 4″ to accommodate the Red Sea Sumps but I also include a 5″ diameter step-up ring that will work with most other filter sock holders (including the one I sell!). In addition to the larger step-up ring, I also throw in a 2.75″ diameter template for cutting circles out of media such as filter floss. The tube itself is 3″ o.d. and approx. 6″ tall.
