Choose from Magi200 / Magi380 and Magi700

The Smarter Way to Service Your NICREW Filter

Is your filter flow slowing down or your water looking cloudy? It’s time for a media change. Most replacement cartridges force you to buy a brand-new plastic housing every time, which is both expensive and wasteful.

Finest-Filters Replacement Kits provide everything you need to fully service your filter without the unnecessary plastic.

Key Features

• COMPLETE REFILL KIT: Each set includes both the Activated Carbon Media Bags (for chemical filtration) and the Black Filter Sponges (for mechanical and biological filtration). Please note: No plastic casing is included.

• CUSTOM FIT FOR NICREW: Precision-cut to fit the internal compartments of the NICREW Magi-200, Magi-380, and Magi-700 series. Simply select your model size.

• REUSE YOUR CASING & SAVE: Designed for the savvy hobbyist. Instead of buying expensive new plastic cartridges, simply replace the internal foam and carbon bag and reuse your existing plastic "pot."

• DUAL-ACTION FILTRATION: The high-density black foam traps debris and fish waste, while the premium activated carbon removes odours, tannins, and yellowing from the water.

• REDUCE PLASTIC WASTE: By only replacing the media that actually wears out, you help reduce single-use plastic waste while keeping your aquarium maintenance costs low.

What’s Included?

• Black Filter Foam(s): High-quality foam designed to trap particulate matter and provide a home for beneficial nitrifying bacteria. (x2 Sponges Included)

• Activated Carbon Bag(s): Filled with professional-grade carbon to polish your water and remove organic pollutants. (x3 Carbon Bags Included)
