Lemecima Aquarium Filter Cartridges, 12-Pack for EZ-Change #2 with Activated Carbon

Lemecima aquarium filter cartridges are replacement elements for EZ-Change #2 and compatible 10–20 gallon power filters, supplied as a 12-pack to support routine aquarium filtration.

• Activated carbon absorbs fine impurities and dust — helps keep aquarium water clearer.
• Thickened filter spray cotton surrounds the cartridge — captures fine particles in the water.
• Pre-assembled construction — replace an old element without assembling cartridge parts.
• Recommended replacement every 2–4 weeks — gives you a regular schedule for maintaining filtration.
• Designed for 10–20 gallon power filters — helps match the cartridge to the correct filter range.

Cloudy-looking aquarium water and fine suspended debris can make routine tank care more demanding. These replacement cartridges combine a cotton filter layer with activated carbon for use in compatible power filters. They are made for regular replacement as part of aquarium maintenance, with the actual interval depending on use.

Which aquarium filters are these cartridges compatible with?

Lemecima cartridges fit EZ-Change #2 filter systems and Aqua-Tech 10–20 power filters. They are intended for 10–20 gallon aquarium filters, not 30–60 gallon filters. Compare your filter type and cartridge size before choosing a replacement.

• Cartridge dimensions: 4.5 x 4.7 x 6 in (11.43 x 11.94 x 15.24 cm).
• Blue filter cartridge.
• Allow for slight size variation from manual measurement.

How does the filter cartridge help keep aquarium water clearer?

The cartridge uses filter spray cotton and activated carbon to capture or absorb fine material in the water. The cotton layer filters dust and other fine impurities, while the carbon absorbs fine impurities and odors. Together, these materials are designed to support clearer aquarium water.

• Filter material: filter spray cotton and activated carbon.
• The cotton layer is thickened.
• Activated carbon is incorporated into the cartridge.

How do I replace a Lemecima cartridge?

Shake and rinse the pre-assembled cartridge, then remove the old filter element and put the replacement in its place. No cartridge assembly is needed. Replace the element every 2–4 weeks, or at least 10–12 times a year; how often it needs changing also depends on actual use.

• Prepare the cartridge by shaking and rinsing it.
• Remove the used element before installing the new one.
• Use the recommended interval as a routine maintenance guide.

What comes in the Lemecima replacement set?

The set contains 12 pre-assembled aquarium filter replacement cartridges. Keeping replacement elements on hand supports the regular change schedule for a compatible filter.

• Quantity: 12 aquarium filter replacements.
• Each cartridge is made for the stated EZ-Change #2-compatible filter range.

This set suits aquarium owners using a compatible 10–20 gallon power filter who want replacement cartridges for scheduled maintenance. Its cotton-and-carbon construction, pre-assembled format, and 12-piece quantity make it a practical fit for routine filter changes; it is not intended for 30–60 gallon filters.
