Ensure effective mechanical filtration and clear water with the Aquatlantis B-BOX Coarse Foam cartridge.
Designed for use in the Aquatlantis B-BOX modular system, this durable foam traps larger particles such as fish waste, food, and plant debris before they reach the biological or chemical stages of filtration.
The open-cell structure promotes excellent water flow while preventing clogging and extending the lifespan of your other filter media. Perfect for both freshwater and marine aquariums, it’s an essential first stage in your filtration setup.

Usage Tips:
