UP AQUA G-059F Filter Cartridge Replacements (2pcs)

This 2-piece pack of triple-layer cartridges replaces the worn media in a compatible UP AQUA filter, combining a sponge layer for mechanical capture, a biological sponge for beneficial bacteria, and activated carbon for clearing tints and odours. Keeping fresh cartridges on hand means you can swap out clogged media before flow drops off and water clarity suffers, which is the most common cause of a tired-looking small tank.

Here is the key habit for Singapore tap water: never replace every layer at once. Our beneficial bacteria colonise that biological sponge, so rinse it gently in old tank water and only renew the mechanical and carbon portions when they are spent. Wholesale changes can briefly knock your cycle and spike ammonia in warm 27-29C water, where bacterial swings happen fast. Stagger replacements and your filter stays stable.

Stock up alongside other filter media. To understand what each layer does, read our filter media guide, and avoid cycle-crashing errors with water change mistakes to avoid.
