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.
Most of my products are made to order and BY HAND! Please allow 10 days for fabrication time (longer for Octo Lids™) Shipping prices listed are to the contiguous U.S. Please contact us if you live elsewhere and want a shipping quote.
