Jeneca replacement filter wool (GLB-01/03/04)

Filter wool is the fine polishing stage that catches the last fine particles your foam misses, and it’s a consumable rather than something you wash forever. These GLB replacement packs, two units per packet, let you keep fresh wool on rotation for the matching Jeneca filters. We stock them because clean wool is what gives you that crystal-clear water look, and the moment it clogs with detritus it starts to choke flow instead.

In Singapore’s warm tanks the fine wool loads up faster than many hobbyists expect, since biological activity runs high at 27-29C and feeds a steady stream of fine waste. We tell customers to treat the wool as the layer they refresh most often, while leaving their biological media untouched to protect the cycle. A quick swap during your water change keeps polishing performance up without disturbing the bacteria doing the real work.
