Upgrade your Aquatlantis filtration system with the Modular Cups (B-BOX) — reusable, eco-friendly filter cartridge cups designed for the B-BOX modular media system. Choose from sizes S, M, or L, and select sets of either 5 pieces or 7 pieces to match your aquarium filter and media setup.
These modular cups allow you to customise and update your internal filter without replacing the full unit — simply insert your chosen media cartridges (mechanical, biological, chemical) into the cups, slot them into the filter, and maintain high performance with minimal waste.
Key Features:
Available in Sizes S, M or L to fit different Aquatlantis filter models.
Sets offered in 5-piece kits (typically size M) or 7-piece kits (typically size L) for full filtration flexibility.
100% reusable modular cups made of recycled plastic — sustainable and cost-effective.
Biodegradable and compostable outer coating on cartridges (when used), promoting environmentally friendly disposal.
Compatible with Aquatlantis BIOBOX®, MINI BIOBOX, and BIO FILTER systems when converted via the B-BOX modular infrastructure.
Usage Tips:
Select your filter model, then choose the matching cup size (S, M or L) for best fit and flow.
Choose kit size: 5-piece set for smaller filters or add-on modularity; 7-piece set for full system upgrade.
Insert your chosen filter media cartridges (sold separately) into the cups before placing into the filter cartridge slot.
Monitor water flow — adding additional cups may reduce flow rate, so always check flow specifications. For older Aquatlantis filters using EasyBOX® cartridges, the conversion kit (7 modular cups) allows upgrade to the B-BOX system.
