The Swell Premium Carbon Filter Media can be used with any external aquarium filters and any pond filters. We advised to replace it every 8 weeks from your filter to ensure maximum efficiency.
This premium carbon can adsorb much more impurities from your water than most carbons on the market today and at a much lower cost. It's important to remove carbon media when administering a treatment to ensure the best results.
It sits inside a zip mesh bag which means you will only have to replace the carbon once you have purchased the bag.
Available in two sizes:-
Small bags - 20x30cm (800g)
Large bags - 30x30cm (1.5kg)
