| The Juwel active carbon sponge cleans the aquarium water of all chemical impurities by absorbing them in its active carbon. Consequently, these chemical impurities will not effect the bacteria - cultures inside the blue sponges. If the carbon sponge is left in the filter too long, it can release the chemicals again into the water. Consequently, it isrecommended to replace the carbon sponge every 4 weeks. The Juwel active carbon filter sponge is suitable for the Juwel internal filter Jumbo. Package conten: 2 active carbone sponge pads. |
