Setup, Compatibility & Care
To install the sponge, first turn off the aquarium filter pump. Remove the old media and slide the new Juwel BioPlus sponge into the corresponding filter basket. Ensure the fit is flush against the walls of the compartment.
Care Instructions
- Rinsing: If the flow rate slows down, gently rinse the sponge in a bucket of old aquarium water during a water change. Never use tap water, as the chlorine will kill the beneficial bacteria living inside.
- Replacement: Replace the sponge every 5 to 6 weeks. Over time, the internal pore structure can become compacted or colonized by bacteria that eventually clog the sponge, requiring a fresh replacement to keep the biological cycle steady.
- Compatibility: This M-sized sponge measures 9.5 x 9.5 x 4.5 cm. Verify your specific Juwel filter model size before purchase.
