Glossary – Activated Carbon
Activated carbon is used as a filter to remove organic contaminants or residual matter from aquarium water.
By virtue of its higher Adsorption qualities, activated carbon can absorb up to for times for chemicals than regular aquarium carbon. You may want to use it for removing any remnant mediations once you complete an aquarium treatment, or even as a regular process to keeping the water clean.
You normally find this as part of the filters themselves or in refill cartridges, but can also be purchased in a loose bag.
Remember to replace it at regular intervals – once you remove it from the aquarium, you can add it to your garden soil where it will release fish wastes beneficial to your plants..
