NICREW Replace Cartridge 700 L/H aquarium filter 🐠

This replacement cartridge for NICREW aquarium filters refreshes filtration media quickly and keeps water clearer between full system cleans. The pack combines foam and activated carbon to trap debris and reduce odours, making maintenance straightforward for small to medium freshwater setups.

Key Points

The cartridge is designed for easy swap-in replacement, helping to maintain mechanical and chemical filtration without rebuilding the whole filter. Foam captures particulate waste while the active carbon adsorbs dissolved organics, which may help to reduce algae-promoting nutrients when used alongside regular water changes. 🐟

Routine care is simple. According to the manufacturer, it is best practice to replace the cartridge monthly to preserve flow and filtration efficiency. Consider that aquarium load and stocking levels influence how quickly media becomes saturated, so heavier bioloads may require more frequent changes. 🧼

Technical Specifications

• Name: NICREW Replace Cartridge Fish Tank Filter 700L/H
• Flow rate: 700 L/h
• Media types: Foam and active carbon
• Recommended replacement interval: 1 month (according to the manufacturer)
• Suitable for: NICREW fish tank filters designed for this cartridge model

Usage Recommendations

Fit the cartridge in place of the old media during routine maintenance, taking care to switch off the filter pump first. Rinse the surrounding filter compartment with tank water to remove loose debris before installing the new unit. For aquariums with sensitive livestock, new cartridges can be pre-rinsed briefly in tank water to remove any fine black dust from the carbon.

If you aim to keep biological filtration stable, avoid replacing all bio-media at once. Swap the cartridge as part of a staggered maintenance routine so beneficial bacteria established elsewhere in the filter or in the substrate are not lost. Also note that activated carbon will not remove dissolved ammonia or nitrite, so continue to monitor water parameters regularly.

Advantages

This replacement cartridge reduces the time spent on maintenance by offering a ready-to-install media pack. It combines the mechanical benefit of foam with the chemical polishing action of active carbon, which can improve water clarity and reduce mild odours between full filter services. The compact format is convenient for hobbyists who prefer quick cartridge changes rather than manual media packing.
