NT Labs Aquarium Activated Carbon, Colour and Toxin Remover, Improves Aquarium Water Quality, Removes Excess Water Treatments, Reduces Aquarium Smells (120g)

【 REMOVES COLOURS, ODOURS AND TOXINS】: Activated Carbon is the highest grade, pelleted activated carbon available ensuring the absorption of colour taint often caused by the tannins in bogwood, toxins and heavy metals found in some water sources and helps to reduce that "river" type smell that can build up in a mature aquarium. 【 USE IN THE EVENT OF A TREATMENT OVERDOSE】: Can be used to remove excess medication at the end of a treatment or in the event of an overdose. 【 EASY TO USE 】: Calculate the volume of your aquarium in litres (Length x Width x Depth (in cm)/1,000). Rinse well in tap water, place in filter media bag provided, and add to a filter compartment. Replace after 6-8 weeks or as water clarity degrades. Remove when treating the aquarium with any medication. 【 FILTER MEDIA BAG INCLUDED 】: Each pack contains a suitably sized filter media bag for ease of use. 【 SUITABLE FOR ALL AQUARISTS 】: The ease of use of Activated Carbon means it is perfect for use by beginners and seasoned aquarists alike.
