## Long description

SILVERLINE KUL29 is an activated carbon filter cartridge designed for use with SJ 1203, SJ 1204 and SJ 1002 aquarium and pond filter units. The cartridge provides chemical filtration by adsorbing dissolved organic compounds, residual chlorine and odours to help maintain clearer water and reduce yellowing or discoloration. As a replaceable media element, the SILVERLINE KUL29 is intended for routine maintenance to sustain water quality and support a healthy aquatic environment.
Advantages
The SILVERLINE KUL29 cartridge delivers targeted chemical adsorption without altering mechanical filtration stages, allowing biological filters to operate more effectively. Its form factor matches compatible filter housings for straightforward replacement and it reduces dissolved contaminants that can affect water clarity and smell. This cartridge is a single-purpose media element that can be swapped during scheduled service intervals to maintain consistent filtration performance.
Suitable for
Home aquariums using filter models SJ 1203, SJ 1204 or SJ 1002
Garden ponds with compatible filter housings that accept replaceable cartridges
Situations requiring removal of dissolved organics, chlorine or mild discoloration and odours
When it may not be suitable
The SILVERLINE KUL29 is not intended to provide mechanical or biological filtration on its own and should not replace media designed for biological colonization or particulate removal. It is not formulated to remove heavy metals, dissolved ammonia, nitrite or nitrate; additional specific media or treatment steps are required for those parameters. For filters that do not match the physical dimensions of this cartridge or systems that require continuous specialized media, this product will not be appropriate.
Key specifications
Media type: activated carbon (chemical adsorption)
Compatible units: SJ 1203, SJ 1204, SJ 1002 (cartridge form factor)
Primary function: removal of dissolved organics, chlorine and odours
Intended use: routine replaceable cartridge for aquarium and pond filters
How to use
Turn off and, if applicable, unplug the filter unit before servicing. Open the filter housing according to the manufacturer's instructions for the SJ 1203, SJ 1204 or SJ 1002 model, remove the spent cartridge and dispose of it responsibly. Insert the SILVERLINE KUL29 cartridge in the correct orientation so that it seats properly inside the housing, then reassemble the unit and restore power. Observe the filter for correct priming and flow; perform regular replacement intervals as part of scheduled maintenance or when water clarity and odour indicate reduced adsorption capacity.
What to consider before purchase
Confirm physical compatibility with your filter model (SJ 1203, SJ 1204 or SJ 1002)
Assess whether chemical adsorption is the right treatment for your water issues versus biological or mechanical media
Plan for periodic replacement as activated carbon loses effectiveness over time
Usage recommendations
Replace the SILVERLINE KUL29 cartridge at manufacturer-recommended intervals or sooner if water clarity or odour does not improve; avoid using carbon simultaneously with some chemical medications unless advised, as carbon can adsorb medication components. Store unopened cartridges in a cool, dry place and follow standard safety and disposal guidelines for spent filter media.
