Octo Cup™

Say NO to socks and 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.

Waterbox – Introducing the world’s FIRST filter cup for Waterbox tanks!!  This will fit the Marine, AIO and Cube models.  The tube itself is 2.25″ O.D. and approx. 6″ tall.

My products are made to order, custom! Please allow up to 10 business days for fabrication time for most products. Because my products are made to order, fulfillment time can rarely take longer. Full custom orders can take up to four weeks to complete. Please let me know ahead of time if this may be an issue. Shipping prices listed are to the contiguous U.S. Please contact me if you live elsewhere and want a shipping quote. Because my products are handmade and/or hand assembled, there may be small irregularities which will not effect the performance of your product.
