Aquarium Sponge Filter Core 4 parts

Sponge Filter core for Aquarium. Must use an air pump, tubing and some sand to add weight. Designed for a 48diameter x 40 height biochemical foam.

The core is built with 4 parts. Base, head, tube and lid. There is a hole at the base foot to fill it up with wet sand, to add weight to keep it sink. So add sand, glue the lid with super glue, put the foam around the base, place the head, run the tubbing inside the upper tube, connect it to the head, insert the upper tube on the head and sink it! I had several foams left alone around so I decided not to waste them and bring that amazing unique core to life. I will never buy sponge filter core again, sorry for my pet shop retailer.

I have recently introduced updated versions of the bottom (v15) and top (v17) to address issues related to tightness and fragility. Additionally, I have incorporated a merged tube/bracket system that prevents the need for adding sand to the base, and instead, securely attaches the hole filter using two suction cups. I no longer use a cap on the base, allowing water to enter and add weight.
