## Long description

Replacement filter cartridge pack for MARINA A131 / 125 Power Cartridge models designed for compatible MARINA internal filter systems. This pack contains two cartridges that provide combined mechanical and biological filtration to capture debris, reduce suspended particles and support the development of beneficial nitrifying bacteria. The cartridges are intended for use in freshwater aquariums to help maintain water clarity and basic biological stability between full filter maintenance cycles.
Advantages
These MARINA replacement cartridges offer a two-stage filtration function in a single element, combining a dense mechanical layer with a porous biological substrate. The cartridges are pre-cut to fit standard MARINA A131 / 125 housings, simplifying replacement and reducing handling time. Using original-format cartridges helps maintain the designed flow rate and filtration area of compatible internal filters, ensuring consistent performance and predictable maintenance intervals.
Suitable for
Freshwater aquariums using MARINA A131 or 125 compatible internal filters
Routine cartridge replacements during regular aquarium maintenance
Small to medium aquaria where mechanical removal of debris and biological filtration are required
Key specifications
Pack quantity: 2 cartridges
Filtration types: mechanical and biological
Compatibility: designed for MARINA A131 / 125 style internal filter housings
Material: multi-layer filtration media combining a fibrous mechanical layer and porous biological substrate
Intended use: freshwater aquarium water filtration
How to use
Turn off the filter and disconnect power before opening the filter housing. Remove the spent cartridge and dispose of it according to local regulations. Insert the new MARINA replacement cartridge into the filter housing in the same orientation as the original, ensuring it seats correctly and does not obstruct flow. Reassemble the housing, reconnect power, and observe the filter for correct water movement. Replace cartridges at regular intervals or sooner if flow decreases or media appears clogged.
Usage recommendations
Replace cartridges every 2–4 weeks under typical aquarium stocking and feeding levels; adjust frequency for heavily stocked or planted systems. Rinse new cartridges briefly in dechlorinated water only if necessary to remove packaging dust. Do not use tap water treated with chloramines or high-temperature water to rinse biological media. Monitor water parameters regularly and perform partial water changes as part of a comprehensive maintenance routine.
