Aquacadabra Replacement Compact Coarse Foam Sponge x2 for Juwel Compact Filters

描述

Please note these are not official Juwel filters but our own alternative at a cheaper price. The BioPlus coarse filter sponge will house some very important filter bacteria, therefore it is recommended that the coarse foam in your Juwel filter is replaced every 3 months to help maintain a healthy filtration system. The stucture of this coarse foam filter give it a larger surface area, ideal for growing the friendly filter bacteria you need for an effective filter system.
