OASE BioPlus Carbon Filter Foam Set – 4 Pieces
The Carbon Filter Set 4 BioPlus for the BioPlus 50, 100, or 200 includes four replacement activated carbon filter foams. The addition of activated carbon to your filtration system allows you to customize filtration to meet the specific needs of your aquarium. Activated carbon effectively absorbs unpleasant substances without endangering aquarium inhabitants. It removes medication residues and other impurities from the water. The filter foam format makes replacement easier than traditional granular carbon.
Filter performance and replacement timing depend on aquarium size, number of fish and plants, and observed decline in water clarity or filter efficiency.

The filter foam fits perfectly in my BioPlus 100. It’s easy to install and the carbon effectively removes medication smells after fish treatments. I’ve noticed cleaner water after a few weeks of use.

Works well with my 50-liter tank. The foam is durable and the carbon absorbs odors and chemicals. I check the filter every 4-6 weeks and replace it when the water starts to smell off.
